  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).   SMA attenuators on the 60 MHz IF signal used in the up-convert chain for Input (3.), Horizontal (1.), and Vertical (2.) Channels.1. 2. 3.

TECHNICAL DOCUMENTATION  PROTECTING PEOPLE AND ASSETS®   DATE: 22 MARCH 2017 | VERSION: 1.4 3 RANGER-X5 RADAR SYSTEM TROUBLESHOOTING, MAINTENANCE, AND CALIBRATION EEC® | COMPANY PROPRIETARY  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.    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  PROTECTING PEOPLE AND ASSETS®   DATE: 22 MARCH 2017 | VERSION: 1.4 4 RANGER-X5 RADAR SYSTEM TROUBLESHOOTING, MAINTENANCE, AND CALIBRATION EEC® | COMPANY PROPRIETARY  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 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 manual
TECHNICAL DOCUMENTATION  PROTECTING PEOPLE AND ASSETS®   DATE: 22 MARCH 2017 | VERSION: 1.4 5 RANGER-X5 RADAR SYSTEM TROUBLESHOOTING, MAINTENANCE, AND CALIBRATION EEC® | COMPANY PROPRIETARY  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.
