IMPORTANT NOTICES
HEALTH AND SAFETY
All personnel are required to study these notices and familiarise themselves with all
applicable safety precautions and bring them to the attention of others in the vicinity.
HIGH VOLTAGE WARNING
CD-0845
LETHAL HIGH VOLTAGES ARE PRESENT IN THE TRANSCEIVER
A current of 100 mA passing through the human body for one second can kill. This can
occur at voltages as low as 35 V AC or 50 V DC. Some equipment in the system uses
electrical power that can be lethal. Whenever practical, before carrying out installation,
maintenance or repair, personnel involved must:
(1)
Isolate the equipment from the electrical supply.
(2)
Make tests to verify that the isolation is complete.
(3)
Ensure that power cannot be accidentally reconnected.
DO NOT OPEN ANY OF THE UNITS WHEN THE RADAR IS OPERATIONAL UNLESS FULLY QUALIFIED TO DO SO.
If it is essential to work on the equipment with power connected, work must only be
undertaken by qualified personnel who are fully aware of the danger involved and who
have taken adequate safety precautions to avoid contact with dangerous voltages.
HEALTH HAZARD
CD-0844
This equipment contains materials which produce toxic fumes when ignited.
The inhalation of dust and fumes or any contact with lubricants when cleaning the
equipment may be temporarily harmful to health, depending on individual allergic
reactions. Components which are broken or overheated may release toxic fumes or dust and
must be treated with caution. Do not inhale the fumes and ensure that the dust and debris do not
enter open cuts or abrasions. It is prudent to regard all damaged components as being potentially
toxic, requiring careful handling and appropriate disposal.
Issue 2

RADIATION HAZARD: NON-IONISING
AERIAL RADIATION HAZARD: INJURY CAN RESULT FROM EXPOSURE TO
THE MAIN BEAM OF A STATIONARY RADAR AERIAL. DO NOT STAND
LESS THAN 2 m FROM THE CENTRAL FRONT FACE OF THE AERIAL.
It is accepted in most countries that no significant hazard is presented by radio frequency
mean power density levels up to 10mW/cm. RF power levels in excess of this may cause
harmful effects, particularly to the eyes.
Users of cardiac pacemakers should be aware that radio frequency transmissions, can
damage some such devices or cause irregularities in their operation. Persons using a
pacemaker should ascertain whether their device is likely to be affected before exposing
themselves to the risk of malfunction.
SAFETY ALOFT
AERIAL ROTATION: BEFORE MAINTENANCE TO THE TURNING
MECHANISM TAKES PLACE, DISABLE AERIAL ROTATION.
When working aloft, ensure that it is brought to the attention of someone in authority at
deck or at ground level and that suitably placed warning notices are posted warning that
work aloft is in progress. Ensure that the means of access aloft is secure and beware of wet or
slippery ladder rungs and working areas.
When working on or near a radar scanner and other moving or r.f. radiating equipment,
ensure that it is switched off and that the fuses have been removed and retained.
PERSONAL PROTECTION
10
Personal protection must be used whenever the possibility of an uncontrolled hazard
exists. For example, a suitable face visor, gloves and a body apron should be worn when
handling cathode ray tubes, as a precaution against injury in the event of breakage.
EQUIPMENT SAFETY
11
Do not run the radar with the rotating joint output disconnected.
12
Removal of printed circuit boards with power connected can damage FETs and
Integrated Circuits.
13
The circuitry used on the equipment PCBs utilises CMOS Integrated Circuits. All the
relevant CMOS precautions must be taken to avoid damage to CMOS circuitry when any
board is removed.

CHAPTER 1
GENERAL DESCRIPTION
INTRODUCTION
The SharpEyeTM Radar combines the latest concepts, technologies and state of the art
performance in surface search capability into a high reliability product for the maritime
industry. Comprising an antenna, gearbox and compact transceiver, SharpEyeTM Radar
provides the mariner with a range of highly sophisticated and flexible operating modes and an
unsurpassed ability to detect small targets such as buoys, yachts and personal water craft, in
moderate to severe clutter environments. SharpEyeTM radically departs from conventional
marine navigation radar practice through the transmission of low power RF pulses and
application of pulse compression and coherent pulse Doppler techniques to provide sub-clutter
visibility of targets.
The SharpEyeTM Radar is available as an X-band Transceiver in upmast configuration
(DTX-A3) and is used with the Low Profile Antenna (LPA-A25).
The SharpEyeTM Transceiver operates at fixed antenna rotation speeds of 22 RPM or
44 RPM for optimum update rate. The antenna rotation speed is preset during installation
and is not selectable by the operator.
The SharpEyeTM Transceiver has a range cell size of between 15 m and 30 m, depending
on the range selected from the display.
Radar control is via a CAN bus to the display system with discrete analogue video, sync,
azimuth and heading line signals to the display.
The SharpEyeTM Transceiver requires 110 V/220 V single phase AC for the transceiver
electronics and 3-phase AC from a Drive Control Unit (GTX-A24) for the antenna
turning motor. The Drive Control Unit uses the 220 V ship's single phase mains to generate a
variable frequency 3-phase output for the antenna turning motor. The frequency of the 3-phase
output determines the antenna rotation speed, and is set by links on installation to provide a 25 Hz
output for 22 RPM operation or a 50 Hz output for 44 RPM operation, provided the input
frequency is 50 Hz. If a 60 Hz input frequency is used the Drive Control Unit must also be
reprogrammed as described in Chapter 5 to provide the correct output frequency.
A transformer can be supplied to allow the Drive Control Unit to be used with 110 V
mains supplies.
The Upmast configuration is shown in Figure 1, and a typical implementation in Figure 2.

SYSTEM DESCRIPTION
Transceiver
The transceiver electronics and the transceiver power supply are mounted in a cast
enclosure with one removable side cover, secured by seven captive bolts. The transceiver
electronics are contained in a unit mounted on the side of the enclosure and the power supply is
mounted on the base of the enclosure. The gearbox and motor are mounted on top of the
enclosure with the antenna secured to the top of the gearbox on a swing casting.
WARNING
THERE IS NO SAFETY SWITCH ON THE UPMAST TRANSCEIVER/TURNING
MECHANISM.
MAN ALOFT SAFETY IS PROVIDED BY AN ON/OFF KEYSWITCH ON THE
ASSOCIATED DRIVE CONTROL UNIT (FOR DETAILS SEE BELOW).
THE ON/OFF KEYSWITCH MUST BE SET TO OFF AND THE KEY REMOVED
BEFORE WORKING ON THE UPMAST TRANSCEIVER/TURNING
MECHANISM.
THE INVERTER IN THE DRIVE CONTROL UNIT MUST BE SET TO REMOTE
OPERATION DURING COMMISSIONING, OTHERWISE THE KEYSWITCH
FUNCTION WILL BE OVERRIDDEN.
10
The gearbox has a hollow output shaft through which the rotating joint (rojo) passes. The
output shaft also incorporates the mounting for the azimuth encoder, which provides
angular position information in the form of azimuth and heading line pulses.
11
The azimuth encoder provides azimuth and heading line pulses to the transceiver, which
uses the data internally. The azimuth and heading line pulses are also opto-isolated to
provide outputs to the display system. There are two sets of azimuth pulses in quadrature (each
set providing normal and inverse outputs with 1024 pulses per antenna revolution) and two
heading line pulses (normal and inverse outputs).
12
The motor and gearbox operate in conjunction with the Drive Control Unit to rotate the
antenna at speeds of up to 45 RPM in winds of up to 100 knots. The motor uses a variable
frequency 3-phase supply of 220 V between phases from the Drive Control Unit.
13
The Drive Control Unit uses the ship's single phase mains, which is fed via an inverter to
generate the 3-phase output. The frequency of the 3-phase output determines the antenna
rotation speed. The Drive Control Unit provides a 'soft start' by controlling the supply frequency
from 0 Hz to the operating frequency over a period of nominally 2 seconds.
Page 1.4
Issue 2
KH1264
Chapter 1
14
The transceiver electronics comprise radar control and timing, waveform generator,
solid state transmitter, duplexer, low noise RF receiver, digital receiver, signal processor
and communications interface.
15
The waveform generator provides frequency modulated pulses at an intermediate
frequency (IF), whose characteristics are determined by the range modes. The IF pulses
are mixed with a local oscillator to provide an RF frequency signal to the solid state transmitter,
which provides an RF output at 170 W peak power to a duplexer located within the transceiver.
The signals from the duplexer are fed via a coaxial cable to the rotating joint and then to the
antenna.
16
Return signals from the antenna are fed through the rotating joint to the transceiver,
which routes the received signal via the duplexer to an internal low noise RF receiver,
digital receiver and signal processor. Sensitivity time control (STC) is applied to the RF receiver
to increase the dynamic range. The transceiver provides one analogue SYNC and one analogue
VIDEO coaxial output to the display system.
17
Internal monitoring of the transmitter and receiver performance is provided, therefore no
external components are required to ensure operation is satisfactory.
18
The power supply, located in the cast enclosure, provides the DC supplies for the
transceiver from the 110 V/220 V single phase mains input. The power supply is
autoranging, so no setting up is required for the input voltage.
Drive Control Unit
19
The Drive Control Unit provides a variable frequency 3 phase supply for the antenna
turning motor. The Drive Control Unit accepts a 220 V single phase mains supply. It
generates a 3 phase supply at either 25 Hz (for low speed antenna operation (22 RPM)) or 50 Hz
(for high speed antenna operation (44 RPM)), set up by links made on installation. The default
input frequency is 50 Hz to provide these output frequencies. If a different input frequency or
output frequency are used, the Drive Control Unit must be reprogrammed as described in
Chapter 5. The Drive Control Unit provides a 'soft start' of nominally 2 seconds, and a 'soft stop'
of nominally 10 seconds for the antenna. This reduces torque when the antenna is started and
stopped. If required, a transformer can be fitted to the mains input to enable the unit to be used
with 110 V mains.
20
The Drive Control Unit has two indicators and a switch on the top of the unit. The
indicators are MAINS ON, which is lit when the single phase mains input is present and
MOTOR ON, which is lit when the 3 phase output to the motor is present. The switch provides a
man aloft safety function, and is key operated. The key can only be removed when the switch is
set to OFF. When set to OFF, the 3 phase output is inhibited, thus preventing the antenna from
rotating. When set to ON the key is captive in the switch and the 3 phase power to the antenna
motor is enabled. Note that when the switch is set to OFF the MOTOR ON indicator will always
be unlit.

FUNCTIONAL DESCRIPTION
Functional diagrams of the transceiver and antenna are shown in Figure 3 and the
interconnections in Figure 4.
TRANSCEIVER
Motor and Gearbox
The antenna motor is driven by a 3 phase supply from the inverter in the Drive Control
Unit. The Drive Control Unit is configured to provide a soft start and a soft stop for the
motor, so that the motor takes a few seconds to reach normal antenna rotation speed and a few
seconds to slow down when stopped. This reduces the start up and stopping torque on the motor.
The motor is connected to the antenna by the gearbox which provides the drive to the antenna.
The Azimuth and Heading Line pulses are generated by the Azimuth Encoder, which is
mounted on the output shaft of the gearbox. Part of the Azimuth Encoder rotates with the
gearbox and part remains stationary with the enclosure. The Azimuth Encoder uses an optical
disc with sensors.
Two heading line pulses (heading line and inverse heading line) and two sets of 1024
pulses per revolution azimuth pulses (each set comprising azimuth and inverse azimuth)
are produced for each rotation of the antenna. The two sets of azimuth pulses are produced in
quadrature (called Q1 and Q2 pulses), with Q2 lagging Q1 pulses by 90° when the antenna
rotates in the normal direction. This allows the azimuth data to be used to detect reverse rotation
of the antenna (which may occur due to windage when the motor is switched off) as Q2 pulses
lead Q1 pulses by 90° when the antenna starts to rotate in the reverse direction. The Azimuth
Encoder is supplied with +15 V, which is used to generate azimuth and heading line output
pulses of +15 V. The pulses are passed directly to the display system via TB1 and also to the
SharpEyeTM Azimuth Interface PCA (DTX-A151), which opto-isolates the signals before they
are routed to the Transceiver (DTX-A115).

Transceiver (DTX-A115)
11
The transceiver uses solid state components and provides a signal generator and
frequency synthesiser, up-converter, solid state RF power amplifier, duplexer, low noise
RF receiver, down-converter, digital receiver, digital signal processor and a LAN interface. The
transceiver produces a peak power output of ³170 W. The solid state design provides excellent
reliability and has no lifed items. Note that the unit is not repairable in the field and must be
returned to the manufacturer for repair. The following description is for information only.
12
The transceiver is capable of transmitting and receiving pulses of RF energy whose
centre frequency is contained in the band 9.22 to 9.48 GHz and is capable of inhibiting
the transmission of pulses of RF energy over an azimuth sector defined by the display system.
Timing Circuits and Azimuth Data Processing
13
There are two reference clock outputs, which output squarewaves with a frequency of
80 MHz ± 80 Hz. The local oscillator is phase locked to the reference clock. All the clock
and timing circuits are derived as multiples of this reference clock.
14
The local oscillator produces a sinusoidal output with a frequency of 640 MHz ± 1.3 kHz.
This is used with the transmit and receive circuits for up- and down-conversion.
Transmitter Circuits
15
The signal generation and frequency synthesis circuits use a waveform generator that
provides frequency modulated pulses at an intermediate frequency. The characteristics
of the pulses are determined by the range and rotation modes, i.e. the instrumented range selected
and the antenna rotation speed selected. The waveform generator employs digital synthesis
techniques and outputs frequency modulated pulses with a centre frequency of 60 MHz ±200 Hz.
The within pulse frequency modulation is phase contiguous.
16
The up-converter converts the IF signals from the waveform generator to RF frequency
in three stages. The bandwidth of the first intermediate frequencies within the up
converter are 60 MHz ±12 MHz and 140 MHz ±12 MHz. The bandwidth of the second
intermediate frequencies within the up converter are 500 MHz ±20 MHz and 580 MHz
±20 MHz. The bandwidth of the third intermediate frequencies within the up converter are
1140 MHz ±20 MHz and 1220 MHz ±20 MHz.
17
The RF frequency signal is fed to the solid state power amplifier, which provides an RF
output at ³170 W peak power to a duplexer located within the transceiver. Note that the
power amplifier stage is switched off between sending each of the pulses in order to maximise
receiver sensitivity. The signals from the duplexer are fed via a coaxial cable to the rotating joint
and then to the antenna.
Issue 2
Page 3.7
KH1264
Chapter 3
Receiver Circuits
18
Return signals from the antenna are fed through the rotating joint to the transceiver,
which routes the received signal via the duplexer to an internal low noise RF receiver,
digital receiver and signal processor.
19
Sensitivity Time Control (STC) is applied to the low noise RF receiver to increase the
dynamic range of the receiver. The noise figure of the receiver is £4 dB, measured at the
output of the analogue to digital converter. The low noise receiver contains the capability to
adjust the mean noise level prior to analogue to digital conversion.
20
The output from the low noise RF receiver is converted to a third intermediate frequency
in three stages. The bandwidth of the first intermediate frequency is 1220 MHz ±20 MHz.
The bandwidth of the second intermediate frequency is 580 MHz ±20 MHz. The bandwidth of
the third intermediate frequency is 60 MHz ±12 MHz.
21
The intermediate frequency is applied to an analogue-to-digital converter which outputs
14 bit two’s complement digitised samples to the digital receiver. The centre frequency
of the digitised samples is 20 MHz ±80 Hz and the instantaneous bandwidth is £20 MHz.
22
The digital receiver translates the signals to the baseband frequency and provides
In-phase and Quadrature (I and Q) outputs to the digital signal processor. The in-phase
and quadrature phase outputs of the digital receiver are both rounded to 18 bits, and the format of
the output is two's complement.
23
The digital signal processor uses digital pulse compression before applying the signals to
the limiting and compensation function. Motion compensation removes the effect of own
ship motion from the received signal vector. The limiting and motion compensation function has
a Doppler output channel and a Logarithmic output channel.
24
The Doppler channel is currently not implemented.
25
The input to the Logarithmic channel is used for video processing. The video processing
function aligns the amplitude data into a contiguous range ordered data stream, aligns the
single bit detection video into a contiguous range ordered data stream and aligns the logarithmic
amplitude data into a contiguous range ordered data stream.
26
The video is converted to analogue video for output to conventional display systems, e.g.
Nucleus 3, Manta and MantaDigital. In the future digital video will also be output from
the LAN link.
27
Due to the characteristics of RACON systems, the processing applied to targets and
objects within the digital signal processor is not suitable for the detection of a RACON.
To solve this, a specific RACON processing channel is included. This enables RACON signals
to be processed and integrated into the surface picture processed video output.

Operating States
28
The transceiver has the following six operating states:
(1)
Off. In this state power is not applied to the transceiver and it is switched off.
(2)
Initialise. When power is applied to the transceiver it enters initialise state. The
transceiver automatically loads any software or configuration files and supplies
DC power to the azimuth encoder. On completion of initialisation the transceiver
switches to Standby state.
(3)
Standby. In this state the transceiver establishes communication with the display
system and reports its status to the display system. The transceiver receives and
acts on commands from the display system and provides azimuth and heading
line data from the encoder to the display system. The transceiver does not radiate
RF in this state.
(4)
Transmit. On receipt of a Run command from the display system, provided the
display system has defined all the operating conditions, the transceiver switches
from Standby to Run state. The transceiver initially outputs an RF signal into the
antenna at low power. This enables the VSWR to be checked without the risk of
damage to the transceiver, e.g. from an open circuit into the antenna. If the VSWR
is within limits then the transceiver automatically switches to full power. If the
VSWR is high, indicating an antenna fault, a warning message is sent to the
display system and the transceiver does not radiate on full power. The radar
returns are then processed to provide radar video to the display system. Note that
the time from switch on to being ready to enter the run state is less than 2 minutes.
(5)
Degraded. The transceiver continuously runs background performance checks
on forward power, reverse power and receiver sensitivity. If any of these
parameters is outside predetermined levels a warning message is sent to the
display system indicating the nature of the fault. The transceiver continues to
operate, but with reduced performance and functionality. The fault should be
investigated at the earliest opportunity.
(6)
Fault. If the performance or functionality is degraded such that the transceiver
cannot operate it enters the fault state and a fault message is sent to the display
system. The transceiver stops radiating RF and there is no video to the display.
Operating Range
29
In either the Transmit or Degraded states the radar operates in one surface picture mode
with a range of interest of 48 nm. The operating range is determined by the Range Scales
selected on the display. 24 nm mode is applied when a range scale of 24 nm or less is selected.
48 nm operating range is selected for range scales greater than 24 nm.

Installation and Setting to Work Parameters
30
The SharpEyeTM Transceiver contains a number of operational settings that are set up
during system installation and setting to work. These operational settings are:
(1)
Rotation Rate. The transceiver supports 2 nominal antenna rotation rates, 22 rpm
and 44 rpm. System behaviour and performance varies depending upon which
rotation rate is selected as the system parameters are adjusted for the different
rotation rates.
(2)
Operating Frequency. The transceiver contains 14 pre-set transmission
frequencies within the operating frequency band. The frequency used for a
particular system is set during system installation and setting to work. The centre
frequencies of each RF band are:
(a)
9.22GHz ±15 kHz.
(b)
9.24GHz ±15 kHz.
(c)
9.26GHz ±15 kHz.
(d)
9.28GHz ±15 kHz.
(e)
9.30GHz ±15 kHz.
(f)
9.32GHz ±15 kHz.
(g)
9.34GHz ±15 kHz.
(h)
9.36GHz ±15 kHz.
(i)
9.38GHz ±15 kHz.
(j)
9.40GHz ±15 kHz.
(k)
9.42GHz ±15 kHz.
(l)
9.44GHz ±15 kHz.
(m) 9.46GHz ±15 kHz.
(n)
9.48GHz ±15 kHz.
(3)
Transmit Inhibit Sector. The transceiver provides one blanking sector that is
configured via the display system. The radar does not transmit RF energy within
the blanking sector.

Chapter 3
Monitoring
31
If the RF output power falls below 100 W the transceiver sends an RF Power warning
message to the display system and switches to the Degraded state of operation.
32
If the VSWR on the RF output is above 2.0:1 the transceiver sends an Antenna VSWR
warning message to the display system and switches to the Degraded state of operation.
33
If the minimum detectable signal rises above a preset level the transceiver sends a
Receiver Sensitivity warning message to the display system and switches to the
Degraded state of operation.
34
If the transceiver detects hardware faults (frequency synthesis or phase locked oscillator
failure), it sends a warning message to the display system and switches to the Degraded
state of operation.
35
If communication between the transceiver and the display system is lost for > 5 seconds
the transceiver switches to the fault state.
36
If the temperature of the RF power transistors in the transceiver exceeds a predetermined
limit, the transceiver sends an Overtemperature warning to the display system and
switches to the Degraded state. If the temperature exceeds a further preset limit the transceiver
switches to the Fault state. As the temperature drops below the predetermined limits the
transceiver returns to the Degraded state and then to normal Transmit operation.
CAN Bus Interface
37
The CAN bus signals to and from the display system are routed via the CAN Adapter
PCB (NNR-A981), which interfaces the CAN bus to the RS232 interface on the
Transceiver (DTX-A115). The CAN Adapter PCB converts the RS232 signals from the
Transceiver into CAN bus signals for routing to the display, and converts the CAN bus signals
from the display to RS232 signals for application to the transceiver.
+15 V Supplies
+15 V from the transceiver is routed to the SharpEyeTM Azimuth Interface PCB
(DTX-A151). The SharpEyeTM Azimuth Interface PCB routes the +15 V to the Encoder
and the CAN Adapter PCB (NNR-A981).
38
Power Supply (45-690-0062-002)
39
The transceiver uses 110 V or 220 V single phase mains, which is passed through a mains
filter before application to the Switched Mode Power Supply. The Power Supply
provides the following DC supplies for the transceiver module:
Issue 2
(1)
+3.3 V at 5.0 A for the digital processing circuits.
(2)
+15 V at 5.0 A for the digital processing and amplifier circuits.
(3)
+13 V at 6.0 A for the amplifier circuits.

DRIVE CONTROL UNIT (GTX-A24)
40
The drive control unit provides 3 phase supplies for the antenna turning motor in the
SharpEyeTM Upmast Transceiver. It accepts a 220 V single phase mains supply and
generates a 3 phase supply at either 25 Hz or 50 Hz with the frequency set internally, either of
which may be selected from the display, or by physical wire links on the Drive Control Unit.
25 Hz is used to provide an antenna speed of 22 rpm and 50 Hz is used to provide an antenna
speed of 44 rpm. If required, a transformer can be fitted to the mains input to enable the unit to be
used with 110 V mains.
41
42
Figure 5 shows the interconnections within the Drive Control Unit. The Drive Control
Unit comprises:
(1)
Inverter (45-690-0033-001)
(2)
Drive Interface PCB (GTX-A104)
(3)
Mains input filter (part of Power Input Cableform GTX-A217)
(4)
Man Aloft Keyswitch (45-613-4205)
(5)
Output filters (ferrite cores - part of Power Output Cableform GTX-A196)
The presence of the mains input is indicated by the MAINS ON neon indicator (LP1) on
the top of the unit being lit.
43
The mains input is passed through the input filter, which slows down the rate of rise of
current input pulses to reduce the generation of interference. The mains is then applied to
the inverter, which converts the single-phase input at 50/60 Hz into 3-phase at 0 Hz to 120 Hz
(variable). The 3-phase output is generated as switched mode power pulses. These pulses are at
the peak output voltage, which is approximately 320 V with 5 kHz switching frequency. The
effective rms voltage at the output varies from 130 V to 230 V AC depending on the antenna
motor load.
44
The output frequency sets the speed of antenna rotation. The output frequency is set to
25 Hz for 22 rpm and 50 Hz for 44 rpm antenna rotation speed. The speed is set at the
inverter on installation and if the inverter is replaced, the new inverter must be correctly set after
repair. Note that the inverter is set on installation to provide a 25 Hz or 50 Hz output using wire
links. The output frequency is also dependent on the input frequency, so that the new inverter
must be programmed for 50 Hz or 60 Hz input as described in Chapter 5. Most of the settings are
the manufacturer's defaults, but others must be set up as specified.
45
The inverter is set to provide an acceleration time of 2 seconds before reaching full speed,
this provides a soft-start function for the antenna on start up. When the power is switched
off, the inverter provides a deceleration time of 10 seconds to slow the antenna rotation. These
functions reduce the torque on the antenna during starting and stopping.
46
The Drive Interface PCB (GTX-A104) provides the control interface to the inverter. It
also provides the interface to external control lines to allow one of the antenna speeds to
be selected by wire links on installation. It uses opto-isolators to allow the control signals to the
inverter to be compatible with the inverter.
Issue 2
Page 3.17
KH1264
Chapter 3
47
The inverter is switched on by applying +12 V to +28 V across PLA pins 1 and 2 on the
Drive Control PCB. The positive voltage is routed via PLC pin 5 to the Man Aloft
Keyswitch (SW1), which is located on the top of the unit. This switch disables the +12 V to +28 V
to the inverter when set to the OFF position, thus switching the inverter off, regardless of the
input condition, provided the inverter has been set for remote operation. The key is removable in
the OFF position only and is captive in the ON position. This enables antenna rotation to be
inhibited to allow safe man aloft working.
WARNING
THE INVERTER MUST BE SET TO REMOTE OPERATION TO ENABLE THE
KEYSWITCH TO SWITCH THE INVERTER ON AND OFF. UNDER NO
CIRCUMSTANCES SET THE INVERTER TO LOCAL OPERATION AS THIS
WILL OVERRIDE THE SAFETY FUNCTION.
48
The voltage from the keyswitch is routed to PLC pin 6 on the Drive Control PCB. When
the +12 V to +28 V is present at PLC pin 6, an opto-isolator on the Drive Control PCB is
switched on, linking PLB pins 1 and 2 to switch the inverter on. When the +12 V to +28 V is not
present at PLC pin 6, either by the absence of the input on PLA pin 1 or by the keyswitch being set
to OFF, the opto-isolator is switched off and PLB pins 1 and 2 are open circuit, thus switching the
inverter off.
49
A MOTOR ON LED (D1) on top of the unit is lit when 3-phase power is available to the
motor from the inverter. Two of the phases from the inverter are passed to the Drive
Control PCB, which converts the signal to a DC level suitable for the LED.
50
Each output wire passes through a ferrite core to reduce the rate of rise of current, which
reduces the generation of interference. The ferrite cores form part of the output cable.
51
The inverter is used with Speed 1 and Speed 2 inputs, which operate in the same way, so
only Speed 1 input is described. Speed 1 switches on an opto-isolator when PLA pin 3 is
connected to the negative side of the start input (PLA pin 2) and +12 V to +28 V is present at PLC
pin 6. The output is used to link the appropriate inverter speed selector terminals. Using Speed 1
input gives a two speed selection, depending on whether PLA pin 3 is connected to PLA pin 2 or
is open circuit. In this application PLA pin 3 is linked to PLA pin 2 for low speed and is open
circuit for high speed. Speed 2 (PLA pin 4) is always linked to PLA pin 2.

Future enhancements will allow the Drive Control Unit to provide the facility to select up
to four antenna speeds, by controlling Speed 1 and Speed 2 inputs from an external
source. This will allow one of up to four preset speeds to be selected to meet the operational
requirements of the system.

CHAPTER 4
INSTALLATION
GENERAL
This section provides installation information for SharpEyeTM X-band Upmast
Transceiver.
Kelvin Hughes, or appointed agents, contracts only to supply the equipment, supervise
the installation and final connection of the equipment. The installation must be made by a
fully qualified Kelvin Hughes Radar Engineer.
Forward planning for positioning the various units of the Radar must be made before any
installation work is carried out. A full survey is required in order to establish the ship’s
fitment. This may be arranged with the Technical Department of Kelvin Hughes or one of the
approved agencies. Details of Agencies worldwide can be found in Publication KH 401.
COMPASS SAFE DISTANCES
Compass safe distances are stated on labels on all units and are as follows:

TRANSCEIVER
One version of upmast transceiver is available, type DTX-A3, which is used with the
Low Profile Antenna (LPA) (LPA-A25).
The transceiver is used with a bulkhead mounted Drive Control Unit (GTX-A24), which
provides the 3-phase power for the antenna turning motor.

Chapter 4
SAFETY NOTES
Observe the Health and Safety Notices at the front of this manual. In
particular, the procedures given in the Code of Safe Working Practices
CP225 MUST be followed. Failure to follow these procedures and to
complete and return the Warranty card will invalidate the warranty on the
equipment.
Safety personnel must ensure that persons do not encroach on the area of work.
Electrical supplies are to be isolated to any part of the platform when mounting an upmast
transceiver/turning mechanism. A suitable safety platform or harness should be used to
avoid personal injury when working aloft.
Electrical supplies in the vicinity of the transceiver are to be isolated during installation.
10
A working platform is to be provided for installing or servicing the assembly. This should
be positioned approximately a metre below the base of the Upmast Transceiver housing
with a guard rail surrounding it.
11
The Upmast Transceiver must be hoisted to the fixing position using a secured block and
tackle or rope strops.
12
The Upmast Transceiver MUST NOT be lifted by the array, but the complete unit
secured and hoisted evenly. The antenna must be installed after the upmast transceiver
has been installed.
WARNING
WHEN WORKING ON THE UPMAST TRANSCEIVER ALWAYS ENSURE THE
ON/OFF SWITCH ON THE DRIVE CONTROL UNIT IS SET TO OFF AND THE
KEY IS WITHDRAWN. THE KEY SHOULD BE RETAINED BY THE
INSTALLER WHEN WORKING ALOFT. REMOVAL OF THE KEY PREVENTS
THE ANTENNA FROM ROTATING.
THE INVERTER MUST BE SET TO REMOTE OPERATION DURING
COMMISSIONING, OTHERWISE THE KEYSWITCH FUNCTION WILL BE
OVERRIDDEN.
THE UPMAST TRANSCEIVER USES A 110 V/220 V MAINS SUPPLY FOR THE
TRANSCEIVER ELECTRONICS. THIS SUPPLY IS NOT ISOLATED BY THE
KEYSWITCH IN THE DRIVE CONTROL UNIT, AND MUST BE ISOLATED AT
THE MAINS ISOLATOR.

Chapter 4
EQUIPMENT LOCATION
UPMAST TRANSCEIVER (DTX-A3)
13
The Upmast Transceiver should be installed in such a position where Blind Arcs, caused
by obstructions, i.e. masts, funnels etc, are eliminated or minimised. Funnels, crosstrees
and other large obstructions can also reflect energy and give rise to spurious echo returns
especially in close proximity to land. Positioning the antenna close to funnels and exhaust gases
can adversely affect antenna performance.
14
The Upmast Transceiver is to be mounted on a rigid platform, which is positioned so that
the rotating antenna is clear of other structures.
15
The primary consideration must be the strength of the support for the Upmast
Transceiver/Antenna assembly. Details of the requirement are described in the following
sub-paragraphs:
(1)
The antenna must be mounted more than 914 mm (3 ft) above any flat surface
greater than the diameter swept by the antenna. It must not be positioned in close
proximity of any magnetic compass or D/F aerial etc.
(2)
Masts, sampsons, posts and rigging of more than 0.6 m (2 ft) diameter can cause
blind sectors. Increasing the distance between the antenna unit and these objects
will reduce the blind sectors that inhibit a good radar picture.
16
The Upmast Transceiver must not be mounted where the temperature exceeds 70oC.
17
The Upmast Transceiver must be kept clear of ship’s flexible communication aerials to
avoid damage to both.
DRIVE CONTROL UNIT (GTX-A24)
18
The Drive Control Unit is designed for bulkhead mounting and must be sited as near the
Transceiver as possible, the maximum cable run between the Drive Control Unit and
Transceiver is 65 m.
19
The Drive Control Unit must be sited to allow removal of the front cover, access to the
cable glands and removal of the key from the keyswitch, which is essential when working
aloft.
OPTIONAL MAINS ISOLATOR (80-261-600)
20
Issue 2
The Mains Isolator must be sited adjacent to the display or in the area of the operators
control room and connected in parallel with the main display.

INSTALLATION
UPMAST TRANSCEIVER (DTX-A3)
WARNING
ENSURE THAT ALL POWER SUPPLIES IN THE VICINITY OF THE
TRANSCEIVER ARE ISOLATED BEFORE ANY INSTALLATION TAKES
PLACE.
21
The SharpEyeTM Upmast Transceiver is supplied in two parts:
(1)
Transceiver with Gearbox.
(2)
Antenna.
22
The SharpEyeTM Upmast Transceiver is fitted with a Low Profile Antenna (LPA-A25).
23
The ship’s mounting structure must be capable of withstanding the high starting and
stopping torque generated by the motor fitted in the upmast transceiver.
24
When mounting the upmast transceiver observe the following:
(1)
Use the fitting pack supplied with the equipment (refer to Figure 3). The fitting
pack contains fixings that have been tested to withstand the stresses detailed in
paragraph 24.
(2)
Recommended tensile strengths and torque loadings for the fixings are stated on
the installation diagram.
(3)
For upmast transceivers mounted in excess of 1.8 m above the deck, it is
recommended that a service platform and guard rail are fitted.
(4)
Use a suitable jointing compound or sealant to prevent corrosion between the
platform and upmast transceivers/turning mechanism.
CAUTION
The Antenna Window Must NOT Be Painted.
(5)
25
Any chipped or damaged surfaces must be painted with polyurethane paint.
With reference to Figures 1, 2 and 3, install the upmast transceiver and antenna following
the procedures below.
26
It is recommended that the antenna is fitted after installing the transceiver/turning
mechanism to avoid damage to the antenna. Only fit the antenna prior to installing the
transceiver/turning mechanism if absolutely necessary, in which case care must be taken to
avoid damage to the antenna when lifting the combined assembly.

Failure to do so may cause the casting to crack when bolts are tightened to the
correct torque.
(4)
Secure the upmast turning mechanism using the noise reduction kit supplied in
the Fitting Kit GTX-A144 (refer to Figure 3) and secure the fittings to a torque of
20 Nm, as specified on Figure 3.
Fitting the Low Profile Antenna
28
It is recommended that lifting slings are used in an arrangement similar to those shown in
Figure 4 to position the low profile antenna on the transceiver/turning mechanism.
CAUTION
When unpacking the Antenna, ensure that the Waveguide is not kinked, crushed or
bent. Support the Antenna near the ends when lifting it out of its packing and when
fitting into position on the Turning Mechanism. Do Not handle the Antenna by the
Waveguide input.
29
To install the antenna, proceed as follows (refer to Figure 1):
CAUTION

CHAPTER 6
MAINTENANCE
INTRODUCTION
This Chapter is divided into three parts:
(1)
Planned Maintenance.
(2)
Diagnostic Maintenance.
(3)
Corrective Maintenance.
PLANNED MAINTENANCE
NOTE: The transceiver runs continuously runs performance checks in the background, and any
degradation in performance is reported as a warning message. There are no routine
operator or maintainer performance checks required on the transceiver.
SIX MONTHLY CHECKS
NOTE: If you detect any problems when carrying out the following routine maintenance
procedures contact the Kelvin Hughes Service Control Centre or your agent for advice.
CAUTION
Always switch the radar OFF, and as an additional precaution, switch OFF the
antenna safety switches when working on the transceiver or antenna.
Antenna
Visually check the front radiating window for damage and soot or dirt. Note that even a
thin layer of soot or dirt can cause serious loss of radar performance. If necessary,
CAREFULLY wipe the antenna front radiating window using soap and water and a soft
non-abrasive cloth. Ensure the window is not scratched or damaged when carrying out this
procedure.
CAUTION
NEVER PAINT the front radiating window.
Transceiver Casing Inspection
Issue 2
Visually inspect that all screws, nuts and bolts are secure and free from corrosion.
Page 6.3

Chapter 6
DIAGNOSTIC MAINTENANCE
WARNING
THIS EQUIPMENT IS NOT FITTED WITH SAFETY INTERLOCKS AND
LETHAL VOLTAGES ARE PRESENT WITHIN THE UNIT. ACCESS TO THE
INTERIOR OF THE UNIT IS ONLY TO BE CARRIED OUT BY A QUALIFIED
TECHNICIAN.
The flowcharts in this chapter provide an aid to fault diagnosis in the transceiver. The
algorithms enable fault diagnosis down to module level and also identify wiring faults.
Entry to the algorithms is via Failure Messages generated by the display.
PRE-REQUISITES
The diagnostic routines in the flow charts assume that the radar has been working, and
that the system is set up for normal operation at the time the fault occurred.
FAILURE MESSAGES
These failure messages appear in the data field of the display monitor if certain signals
are missing. One or more of the following messages may be displayed on the display
system:
(1)
No Sync. Indicates that the display is not detecting sync pulses from the
transceiver.
(2)
No Video. Indicates that the display is not detecting video from the transceiver.
(3)
No Azimuth. Indicates that the display is not detecting azimuth pulses from the
transceiver.
(4)
No Heading Line. Indicates that the display is not detecting heading line pulses
from the transceiver.
The following messages are supplied from the transceiver via the CAN bus, which may
switch to degraded mode of operation (low power output, low sensitivity etc) or fault
mode:
(1)
Receiver Sensitivity Low. This indicates that the minimum detectable signal is
³TBD dB, indicating a receiver fault. The transceiver continues operating in the
degraded state. Should the minimum detectable signal be ³TBD dB, the
transceiver will enter the fault state.
(2)
Antenna VSWR High. The transceiver has detected a high reverse power and
hence VSWR. This indicates that there is a mismatch in the transceiver output to
the antenna, e.g. an antenna or rotating joint fault.
(3)
RF Power Low. The transceiver has detected low power on the output. If the
power is 3 dB below normal this indicates that one of the two RF output
transistors in the transceiver has failed, i.e. a fault in the transceiver unit. The
transceiver continues operating in a degraded state on half power. Should the
second RF output transistor then fail, the transceiver will enter the fault state.
Page 6.4
Issue 2
KH1264
Chapter 6
(4)
PLO Lock. Indicates that the phase locked oscillator has developed a hardware
fault.
(5)
Synth Lock. Indicates that the frequency synthesiser has developed a hardware
fault.
(6)
Transmitter Over-temperature. This indicates that the temperature of the RF
power transistors is high, indicating a fault in the transceiver.
Fault diagnosis algorithms covering these failures is provided in Figure 3.
TEST EQUIPMENT
Fault location is to module replacement level only. The only test equipment required for
fault finding is a high impedance Multimeter.
PREPARATION FOR FAULT DIAGNOSIS
WARNING
THIS EQUIPMENT IS NOT FITTED WITH SAFETY INTERLOCKS AND
LETHAL VOLTAGES ARE PRESENT WITHIN THE UNIT. ACCESS TO THE
INTERIOR OF THE TRANSCEIVER IS ONLY TO BE CARRIED OUT BY A
QUALIFIED TECHNICIAN.
CAUTIONS
(1)
Handling Of Electrostatic Sensitive Semiconductor Devices.
Semiconductor devices used in the equipment are liable to damage due
to static voltage. Observe the following precautions when handling
these devices in their unterminated state, or modules containing these
devices.
Persons removing modules from an equipment using these devices
should be earthed by a wrist strap and a resistor.
Soldering irons used during repair operations must be low voltage
types with earth tips and isolated from the mains voltage by a double
insulated transformer.
Outer clothing worn must be unable to generate static voltages.
Printed Circuit Boards (PCBs) fitted with these devices must be stored
and transported in anti-static bags.
Fit new devices in a special handling area.
For detailed information, refer to British Standard BS 5783 or other
equivalent standard.

To access the units inside the upmast transceiver, remove the side cover of the
transceiver. This allows access to the transceiver and the power supply and allows the
LEDs on the PSU Sense PCB and CAN Adapter PCB to be seen.
WARNING
IT IS DANGEROUS TO RUN THE TRANSCEIVER WHEN UPMAST AS THE
ANTENNA IS ROTATING AND RF IS RADIATED. UNDER NO
CIRCUMSTANCES SHOULD THE MAINTAINER BE UPMAST WHEN RF IS
RADIATED AND/OR THE ANTENNA IS ROTATING. THEREFORE ALL
CHECKS MUST BE MADE WITH THE TRANSCEIVER IN STANDBY MODE,
THIS WILL LIMIT THE CHECKS THAT CAN BE MADE WHEN THE
TRANSCEIVER IS SET TO RUN.

CHECKS AFTER UNIT REPLACEMENT
38
Any maintenance, or rectification, involving the replacement of PCBs or Modules within
the Transceiver involves certain procedures to bring the Transceiver up to full working
order. The PCBs and Modules have been factory tested, and preset, and do not require any
adjustment. Therefore, no setting up procedures are required for the transceiver. However, if the
inverter in the Drive Control Unit is replaced the new inverter must be set up with the same
parameters as the replaced unit.
39
The following paragraphs and sub-paragraphs are procedures that the maintainer or
installer must follow to gain satisfactory performance of the equipment.
WARNING
DURING THESE PROCEDURES THE ANTENNA IS REQUIRED TO BE
ROTATING, CARE IS TO BE TAKEN IF CHECKS ARE TO BE MADE AT THE
TRANSCEIVER.
Transceiver
40
There are no setting up procedures required for the transceiver after a unit has been
replaced.
Drive Control Unit
