The National Weather Service (NWS) is conducting market research for replacement of the current SIGMET RCP8/RVP8 radar receiver and signal processor throughout the fleet of 160+ WSR-88D (a.k.a. NEXRAD) weather radars. These components have become obsolete and will not be supported by the manufacturer after December, 2015. The replacement system must be available for testing in 2014, and be ready for production in 2015. The replacement system shall control the transmitter, pedestal, and power systems, along with monitoring various sensors and switches for alarms and performance data. The replacement system will input 2 receive IFs for Dual Polarization (DP), digitally filter and create IQ data for both data streams, and then process the IQ data into radial moments and DP variables for transmission to the Radar Product Generator. More data, requirements, and white papers can be found on: http://ftp.roc.noaa.gov/pub/Signal_Processor_RFI. GENERAL: The minimum requirements of the replacement system include: 4 IF inputs at 57.5491MHz with SMA connectors: COHO, Radiated Burst Pulse Sample, Horizontal IF, and Vertical IF Digital Matched Filtering from 100KHz to 700KHz Minimum 93dB Dynamic Range with 600KHz matched filter bandwidth; input power of at least +23dBm shall not cause damage Shall not use Automatic Gain Control Data acquisition minimum 16 bit 100MHz Phase locking to burst pulse Access to I/Q data for archiving Ability for the government to work with raw I/Q for maintenance and scientific investigation Calibrations Noise measurements Troubleshooting routines Execute NEXRAD Volume Control Patterns (VCPs); allows calibrations between VCPs and the ability for the NWS to design and insert these calibrations. Output 8 triggers with 50nsec timing accuracy. Must handle arbitrary trigger sequences and Pulse Rate Intervals to support Staggered PRTs and NEXRADs Batch Mode. 7 bits Phase control to support phase encoding At least 2 pulse widths 3 bits tied to PRF/PRI for Pulse Regulation of the Post Charge Regulator Signal Processing to produce NEXRAD moments (Reflectivity, Velocity, and Spectrum Width) and Dual Polarization variables (Differential Reflectivity, Correlation Coefficient, and PHI) with accuracy to NEXRAD specifications Clutter filtering capability to meet NEXRAD specifications (the system currently uses SIGMETs GMAP clutter filter) Ability for the government to insert custom signal processing code such as: Clutter Mitigation Decision (CMD) Point Clutter Filtering SZ-2 Phase Encoding NEXRAD Split Cuts Sector Blanking Clutter Maps Digital pedestal servo control; support 14 bit encoders and output voltage to control azimuth and elevation Input data and output commands to and from sensors, power supplies, switches, Automatic Transfer Switch, and other electronic... more info : Location : United States BidDate : 9/10/2012 Tender Country : United States Tender Type : Tenders Tendering Authority : Department of Commerce Tendering Authority Address : Address: 325 Broadway - MC3 Boulder Colorado 80305-3328 United States Point Of Contact: Chad M.
