The Enterprise Electronics Corporation (EEC) Ranger-X5 radar system is a new generation, X-
band (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.
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.
The 1-meter variant shown in Figure 1 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 1. 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
analysis with extremely high precision in all modes of operation. Normal radar control and data
processing utilizes the EDGE Radar Control and Analysis Software. A separate technical
manuals 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 system 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.

standard ModbusTCP for communications. The Radar Control Unit is loaded with Cobra
Software (See Section 3, RCU Cobra Software).
Implementation of command and control of the pedestal is over the Ethernet link from the Radar
Control Unit PC (COBRA Application software) all of the other components in the Control Cabinet
and the Pedestal Unit. The control of the azimuth and elevation servo is directly through an
Ethernet connection to the Servo Controller Assembly.
Position commands route to the Servo Controller from the COBRA software system based on
commands from either the Local Control Interface (LCI) or the remote host operator. A position
command invokes a command interpreter script in COBRA that sends the appropriate command
to the pre-loaded servo control module. The Servo Controller has an extensive standard
command and control set and an extended command set for use with radar servo systems.

1.1.1.1. COBRA RCP Module
The COBRA Radar Control Processor (RCP) module controls the radar hardware through a
series of coordinated and supervised hardware Analog and Digital control modules. These I/O
modules connect to the RCU by Ethernet. The Ethernet communication layer between the RCU
and the distributed modules is functionally isolated from any point beyond the RCU so there is
no danger to having a remote host attempt to communicate directly with the hardware control
modules.
The COBRA RCP software is hardware independent through a software abstraction layer. This
allows easy transition to other vendors and products based on availability and features
In order to assure accurate and complete time stamping of each command, response, and status,
each module comprising the RCU is synchronized using the Network Time Protocol (NTP).
Additionally, filters and other integrity checks within the RCU and associated software elements
ensure that any command, response, error message, or status message is appropriately logged
and repeated entries are avoided.
1.1.1.2. COBRA HCI Module
The COBRA HCI software module operates at the gateway between the RCP module and the
EEC EDGE Radar Host computer.
1.1.1.3. COBRA LCI Module
The Local Control Interface (LCI) module is a computer based local control and operator interface
to the COBRA program functions. In this configuration, the LCI runs on the same computer as
the COBRA software. The user display shares the standard commercial keyboard and video
monitor unit with the IQ2-DSP and EDGE Host computer.
The software communicates with various radar components through the COBRA application
software in order to provide user commands to the system and reflect control and status data to
the user. Such data includes but is not limited to azimuth and elevation position, power levels,
and voltage/current measurements. The ability to monitor the radar performance over Ethernet
connections provides the flexibility and opportunity to monitor the radar from virtually anywhere.
LCI presents the radar control information as familiar indicators and controls on the computer
screen as a virtual control panel. Common indicator styles include the LED, round gauges and
seven-segment digital readouts. Some indicators switch views when clicked. Interaction is
through the keyboard and touch pad.
1.1.2. IQ2 Digital Signal Processor (Unit 1 A2)
The IQ2 DSP consists of a PCIe card in a high-performance Host Computer used for signal
processing deployed in the Control Cabinet. This design of the computer and PCIe card ensures
the highest performance available, as well as for flexibility in adapting to various radar system
configurations. The DSP receives digital I/Q over the high-speed optical link from the IQ2-IFD,
passes this data to the high-speed server for moments processing.

1.1.2.1. IQ2 Host Computer (Unit 1 A2 A1)
The IQ2-DSP Host Computer is equipped with a powerful, state-of-the-art, signal processor that
receives In-Phase and Quadrature (I/Q) data from the IQ2-IFD coming in real time. The Signal
Processor elaborates the real-time I/Q data to create the required single and dual polarization
meteorological moments.
The IQ2-DSP consists of a PCIe communications card plugged into a high-speed server. The
PCIe card receives the high-speed optical link from the IQ2-IFD, passes this data to the high-
speed server for the processing of meteorological moments, and provides additional interfaces
that may be required to support other radar-site systems.
The IQ2-DSP Host Computer processes the I/Q data stream, already broken into range-gate
intervals, with floating-point algorithms to provide all required moments. The server also provides
all the configuration and control signals to all of the components in the IQ2-DSP system.
The IQ2-DSP Host Computer is a Linux based standard industrial PC. The standard mode of
operation is the well-defined, proven pulse-pair method of Doppler radar data processing that
produces the standard data moments of:
• Uncorrected Reflectivity (U)
• Corrected Reflectivity (ZH)
• Vertical Reflectivity (Zv)
• Velocity (V)
• Spectrum Width (W)

When processing dual-polarization data, the IQ2-DSP also produces:
• Differential Reflectivity (ZDR)
• Differential Phase ( DP)
• Specific Differential Phase (KDP)
• Correlation Coefficient ( HV)
• Linear Depolarization Ratio (LDR)
The standard IQ2-DSP algorithms for the horizontally and vertically polarized channels include
but are not limited to the following:
• Thresholding: Noise, SQI 1& 2, SIGPOW, CCOR, & RHOHV
• Speckle Remover: Z, V, W, & DP
• Averaging: Time and Range
• Doppler Clutter Filters: Time- and Frequency- Domain
• Pulse-Pair Processing
• Discrete Fourier Transform (DFT) Processing
• Staggered PRT Processing or Dual PRT (DPRT)
• Second Trip Processing
• Range-Doppler Dilemma.
Each moment for the current mode of operations routes to the EDGE radar product generator for
further processing and display.
The IQ2-DSP produces the IF transmit pulse input to the RF/IF Up-Converter Assembly in the
Modulator Cabinet. The IQ2-DSP is the master radar synchronizer using a very stable, accurate
trigger generator to produce the system control and timing signals during normal REMOTE and
LOCAL operations.
1.1.2.2. IQ2 DSP PCIe Board (Unit 1 A2 A2)
The EEC IQ2-DSP utilizes a PCIe used for signal processing deployed in the Control Cabinet.
This IQ2-DSP Host Computer and PCIe card design allows for the highest performance available,
as well as for flexibility in adapting to various radar system configurations. The IQ2 IFD is in an
RF Enclosure above the elevation rotary joint. This configuration ensures system optimization
for low transmit and receive losses, as well as for very high data throughput.
1.1.2.3. IQ2 Connector Panel (Unit 1 A2 A3)
The connector panel allows the IQ2 Digital Signal Processor to connect with and communicate
with the IQD-IFD and the EDGE workstation.
1.1.3. Keyboard Video Monitor (Unit 1 A3)
The Keyboard/Video Monitor (KVM) is a control unit that allows access to multiple computers
from a single keyboard, video monitor, and mouse console. The configuration of the KVM allows
it to control the RCU and IQ2-DSP. A local host computer (EDGE) also connects to the KVM.
The cover had a built-in LCD display, and the keyboard and touchpad are built-in to the base.
The KVM module fully integrates into the cabinet and can slide out and open for use.

1.1.10.1. Lightning Protection Module (Unit 1 A10 A1)
(See Figure 13, Point 1)
The lighting protection module protects the main Ethernet input from outside the Ranger-X5 radar
system.
1.1.10.2. Contactor, 3-Phase, 24VDC (Unit 1 A10 K1)
(See Figure 13, Point 4 and Figure 14)
The Contactor (K1) receives DC power from the Safety Replay (K2). When DC power is not
available, the Contactor (K1) is open (Normally Open) it removes all AC power to the remaining
power supplies on the DC Power Distribution Plate. This ensures the power in the pedestal is off
and the system stops radiating and the antenna stops moving.
Figure 14. Contactor (226-0516)
1.1.10.3. Safety Relay (Unit 1 A10 K2)
(See Figure 13, Point 3)
The Safety Relay (K2) receives DC power from the 24VDC Power Supply (PS1). The Safety
Relay receives command and control to open or close DC power output to the Contactor (K1)
from the E-Stop Control Switches on the E-Stop Panel (Unit 1 A12) and/or on the Pedestal Plate
Enclosure Assembly (Unit 2 A1 A5).
When an E-Stop Button is depressed, the Safety Relay stops sending DC power to the
Contactors (K1) and it opens. When the Contactor (K1) is open, it removes all AC power to the
remaining DC Power Supplies (PS2, PS3, and PS4).
