■ ATA (Automatic Tracking Aid)
By tracking automatically the target chosen by the cursor key, the closest point of approach (CPA) and the time to
closest point of approach (TCPA) limit of a own ship and a target are calculated.
ATA is the function to tell about to alarm sound, when both CPA and TCPA becomes below a setting value (the approach watch area).
The range of the target which can be registered is taken as a target with a highest luminosity level of 0.2–16 miles.
• Max. 10 targets can be plotted on the screen.
• Plot positions shall be identified by an approved symbol mark (p. 20) and associated plot number.
• The vector origin will move across the screen at a rate and direction defined by the calculated true or relative

BASIC RADAR THEORY
Radar uses a form of electromagnetic radiation, which like light, can be reflected. Because of this property, some
objects may cause false echoes on the screen where in fact no targets actually exist.
These echoes may appear if a large vessel, bridge, or tank is in proximity. Operators should be familiar with the effects of these phenomena. In some cases, echoes can be reduced.
■ Side-lobe echoes
Radiation can escape on each side of the beam inside
the lobes. If a target reflects this radiation, it will be displayed on the screen as an echo.
Main beam
Side-lobe echoes usually occur at short ranges and as
a result of large (strongly reflective) targets. They can
be reduced with proper adjustment of the [SEA] control.
See p. 10 for the [SEA] control.
Side lobes
True
echo
False
echoes
■ Indirect echoes
Indirect echoes may be returned from either a passing
ship, or returned from a reflecting surface, such as a
mast on your own ship.
An indirect echo from a reflecting surface will appear
on a different bearing from the direct (true) echo, but
the distance will be approximately the same for both.

BASIC RADAR THEORY
■ Multiple echoes
Multiple echoes may appear when a short-range and
strong echo is received from a ship, bridge, or breakwater.
Multiple echoes will appear beyond the target’s true
echo point on the same bearing of a large target. They
can be reduced with proper adjustment of the [SEA]
control.
See p. 10 for the [SEA] control.
False echoes
True echo
Own ship
Another ship
■ Minimum range
Detection at short range is very important. Minimum
range is determined primarily by transmitter pulse
length, vertical beam width and height of the scanner
unit. The shorter the transmission time, the quicker the
return echoes can be received and their distance measured.
The ability to see targets very close to the ship is decreased if the scanner is mounted too high off the
water, because the bottom of the vertical beam of the
scanner cuts off nearby targets.
Vertical beam width
This target can not be recognized with radar.

BASIC RADAR THEORY
■ Blind and Shadow sectors
Blind or Shadow sectors may exist because of obstructions such as masts, derricks or stacks. An obstruction may throw either a complete or partial
shadow as shown in the diagram below. If a target is in
a shadow sector, target echoes may not appear on the
screen.
Shadow sector
When tall and massive targets such as a large island
are located at close range also shadowed without producing any echoes. This phenomenon is called blind
sector. It is very important to know the bearings and
widths of all shadow sectors caused by your own
ship’s obstructions.

■ Target resolution
Target resolution is determined by the horizontal beam
width and transmit pulse width. Sometimes it is difficult
to detect two targets which are separated by short distances or which are in the same direction.
D Distance resolution
D Direction resolution
When two targets are separated by more than the
pulse width, they appear as two echoes.
When two targets are separated by more than the
horizontal beam width, they appear as two echoes.
When two targets are not separated by more than
the pulse width, they appear as 1 echo.
When two targets are not separated by more than
the horizontal beam width, they appear as one echo.

e Check cables and terminal connections.
■ Scanner unit maintenance
WARNING: BE SURE the power is OFF before
working on the radar.
D Cleaning
q Wipe the surface of the scanner with a clean soft
cloth.
• DO NOT use strong solvents such as benzene or alcohol.
w Check that there is no drift or caked salt.
• A heavy deposit of dirt or caked salt on the painted surface of the upper scanner unit will cause a considerable
drop in radar performance.
e Check for cracks or deterioration of the rubber
packing and replace it if necessary.
D Painting (MR-1000TII only)
To prevent the corrosion, paint the surface of the
scanner body (except the antenna unit) twice a year
or more.
D Mounting
Check the mounting bolts of the scanner unit and
tighten if necessary.
■ Display unit maintenance

RADAR OPERATOR WARNING
Icom requires the radar operator to meet
the FCC Requirements for Radio Frequency Exposure. A slotted waveguide
array antenna with gain not greater than
W ARN ING
27 dBi must be mounted a minimum of 5.5
meters (measured from the lowest point of the
antenna) vertically above the main deck and all possible personnel. This is the minimum safe separation
distance estimated to meet all RF exposure compliance requirements. This 5.5 meter distance is based
on the FCC Safe Maximum Permissible Exposure
(MPE) distance of 3.5 meters added to the height of an
adult (2 meters) and is appropriate for all vessels.
For watercraft without suitable structures, the antenna
must be mounted so as to maintain a minimum of 1
meter vertically between the antenna, (measured from
the lowest point of the antenna), to the heads of all persons AND all persons must stay outside of the 3 5
meter MPE radius.
Do not transmit with radar and antenna when persons
are within the MPE radius of the antenna, unless such
persons (such as driver or radar operator) are shielded
from antenna field by a grounded metallic barrier. The
MPE Radius is the minimum distance from the antenna axis that person should maintain in order to
avoid RF exposure higher than the allowable MPE
level set by FCC.
FAILURE TO OBSERVE THESE LIMITS MAY
ALLOW THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH
EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT.
IT IS THE RESPONSIBILITY OF THE RADAR OPERATOR TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT
ALL TIMES DURING RADAR TRANSMISSION. THE
RADAR OPERATOR IS TO ENSURE THAT NO BYSTANDERS COME WITHIN THE RADIUS OF THE
MAXIMUM PERMISSIBLE EXPOSURE LIMITS.
Determining MPE Radius
THE MAXIMUM PERMISSIBLE EXPOSURE (MPE)
RADIUS HAS BEEN ESTIMATED TO BE A RADIUS
OF ABOUT 3.5 M PER OET BULLETIN 65 OF THE
FCC.
THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM POWER OF THE RADAR AND ANTENNAS
WITH A MAXIMUM GAIN OF 27 dBi ARE USED FOR
A SHIP MOUNTED SYSTEM.
