RANGER X5 TUNING PROCEDURE
The power amplitude of the amplifier is completely dependent on the level of RF drive supplied
to the amplifier. The RF drive is dependent on several factors. Drive amplitude is affected by
the local oscillator output (which is adjustable in increments of 0.5 dBm), the 60 MHz IF output
amplitude which derives from the output of the IFD, and the frequency to a lesser degree due to
loss in the cabling.
The system will have a minimum output of 500 Watts (56.989 dBm), with an allowable overage
of 0.792 dBm (Total Overage 600Watts (57.781dBm)). The maximum RF drive into the
amplifier is +14 dBm, however the gain of two amps will not always yield the same output. Due
to some minor inconsistencies in the gain and losses of the amplifiers, each amplifier may have
its RF input drive increased or decreased. In other words, we have the ability to manipulate the
RF drive to each amp independently from one another.
During factory testing the gain is set to around 10 dBm roughly to use as a starting point. The
output of the amplifier is measured using a calibrated peak power meter (sensor) during this
time. The RF drive is then adjusted through the use of SMA attenuators on the 60 MHz IF
signal used in the up-convert chain for Input, Horizontal, and Vertical Channels. The local
oscillator amplitude can be changed if necessary, however this will affect the drive to both
amplifiers therefore, the local oscillator is set to a standard amplitude (typically 9 dBm), and
drive adjustments are made by increasing or decreasing the 60 MHz amplitude as necessary to
achieve the desired output power from the transmitters (Horizontal / Vertical).

TECHNICAL DOCUMENTATION
The Enterprise Electronics Corporation (EEC) Ranger-X5 radar system is a new generation, Xband (3 cm), Adaptive Polarization Doppler Weather Surveillance Radar that fills the gap between
high-cost, high-power traditional radar systems and the passive ground-station weather sensors.
The system uses relatively low power solid-state transmitters and pulse compression technology
to attain nearly the same performance capabilities of much more expensive traditional radar
systems. The Ranger-X5 employs Adaptive Dual Polarization (ADP) techniques to allow
Alternating or Simultaneous Dual Polarization capability with total control over the transmission
polarization state using dual independent coherent transmitters.
The entire Ranger-X5 design concept emphasizes precision, stability, reliability, and value using
proven solid-state technology combined with the most advanced motion control system ever
conceived for weather radar. The sealed, lubricated for life, mechanical drive system in the
Ranger-X5 has an MTBF in excess of 180,000 hours without the need for routine maintenance
or lubrication. The motion system provides extremely high torque to weight ratios for outdoor
operation and greater than 40 arc-second position accuracy.
Advanced configurations and networks of systems are available that meet all of the requirements
for special missions, such as aviation or hydrological forecasting applications.
The flexible architecture and system design facilitates automatic remote operations, ensures
minimal maintenance costs, and provides maximum configurability to meet specialized customer
needs. The Ranger-X5 is designed for continuous (24 hours/day), unattended operations at
remote locations, providing the full suite of polarimetric radar data for local single-site operations,
as a member of a network with predefined product contributions or, as the manager of a network
of remote users providing specific radar products to suite the individual user’s needs.
Figure 1. Outdoor Control Cabinet
The Ranger-X5 radar system is a lightweight, high performance system designed for tactical
grade deployments on a wide variety of fixed and mobile platforms. This densely packed system
provides stability, stiffness, position accuracy and raw power directly coupled to the payload.

TECHNICAL DOCUMENTATION
The 1-meter variant shown in FIGURE XX is capable of supporting full operation in sustained
winds up to 75 mph, and with wind gusts to 90 mph. To deliver radar and motor cooling, the
system provides for water-cooling using naval shipboard cooling techniques.
Figure 2. 1.8 Meter Ranger-X5 Variant
The standard Ranger-X5 system configuration includes an elevation over azimuth pedestal
providing on-board, environmentally sealed, and controlled electronics housing for the
transmitters, receivers, and signal digitizer in conjunction with a NEMA 4 grade environmentally
controlled ground interface enclosure. The ground interface contains the system power supplies,
EEC IQ2 signal processor, Local Control Interface (LCI) station, Radar Control Unit (RCU)
Computer running EEC COBRA software, EEC EDGE software system workstation, and
associated communication interfaces. The ground interface enclosure is not required with
customer furnished facilities.
The standard configuration uses two 500-Watt transmitters located on the pedestal above the
elevation rotational axis to support Dual Polarization operation. This design eliminates the need
for waveguide switches, waveguide rotary joints, or a power splitter, allowing for complete
diversity in H/V measurement schemes and minimum path loss in both the transmission and
reception path.
The radar system provides standard precipitation intensity, turbulence, and velocity modes of

describes the functions of EDGE.
The transmitter provides a 500W peak RF power pulse (in each channel) with an adjustable pulse
width from 0.2 and 100.0 microseconds (µs), providing excellent weather detection at range in all
modes. The transmitter radiates in staggered Pulse Repetition Frequency (PRF) modes at 3:2,
4:3, or 5:4 ratio allowing dual PRF sampling by the digital signal processor to produce maximum
unambiguous velocities of up to ≥90 meters/second.
The EEC IQ2-IFD Intermediate Frequency Digitizer ingests and digitizes the received radar return
in 16-bit resolution. The receiver design utilizes state-of-the-science components to optimize
detection sensitivity, bandwidth, dynamic range, measurement accuracy, and useful life.
The IQ2-IFD converts the analog receiver IF signals into the digital domain. The IQ2-DSP Digital
Signal Processor receives the digitized Inphase / Quadranture (I/Q) data via the PCI receiver
card. The I/Q data stream is pre-processed and polar rays of meteorological moments are
generated. The ray data is sent via a 1Gbit TCP/IP connection to the IQ2-DSP Signal Processor
for storage and further processing. The IQ2 design optimizes detection sensitivity, bandwidth,
dynamic range, measurement accuracy, and useful life.
The IQ2-DSP is the central data processing point for the radar. The IQ2-DSP is an advanced
scientific computer system utilizing the Linux operating system and employs advanced
scientifically validated algorithms. The standard mode of operation is the proven pulse-pair
method of Doppler processing to produce the standard data moments of Uncorrected Reflectivity
(U), Corrected Reflectivity (ZH), Vertical Reflectivity (ZV), Velocity (V), and Spectrum Width (W).
In addition to the standard base Moments the Ranger-X5 provides the Polarimetric Base
Moments Differential Reflectivity (ZDR), Differential Phase (ΦDP), Specific Differential Phase
(KDP), Correlation Coefficient (ρHV), and Linear Depolarization Ratio (LDR), (where applicable).
The derived moment of rainfall (R) is also included.
General system control utilizes the standard EEC Radar Control Unit (RCU). The RCU is used
to correlate and process BITE information from the various modules and procedures, control the
antenna pedestal operational parameters and perform basic radar control. The RCU integrates
closely with the IQ2 Digital Receiver and IQ2 Digital Signal Processor, communicating by
standard Ethernet Protocol.
The radar system design allows for easy maintenance and has a manually selectable
local/remote mode to permit maintenance personnel to gain local control of the radar system.
Local control is implemented on a Local Control Interface (LCI) Display using a system of menus
and status screens. With the automatic calibration functions and easily accessible system test
points, any necessary system testing, calibration, or repair is easily accomplished with minimum
down time.
