A -- DESIGN/DEVELOPMENT/TESTING OF SOFTWARE SOL NRMGL000900288MB POC Michelle Bernal, Purchasing Agent, (303) 497-3983 or FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisition Management, Michelle.A.Bernal@noaa.gov. The National Oceanic & Atmospheric Administration, Environmental Technology Laboratory (NOAA/ETL) requires a software upgrade for five currently deployed MilliMeter (wavelength) Cloud Radars (MMCRs). These radars were originally produced by ETL using software for instrument control and signal processing that was developed for radar wind profilers under a Cooperative Research and Development Agreement (CRADA) with Radian International. The current requirement is to upgrade the MMCR's signal processing system to increase processor efficiency from as low as 5% to at least 90% and to add a cross-polarization channel to the data stream. The contractor will be responsible for the following work: (1)write software drivers and communications software to enable a Radian 12-bit analog-to-digital (A/D) card and interface and a Spectrum 5-processor C40 Digital Signal Processor (DSP) card to function properly and efficiently within Radian's proprietary POP4 software environment (host) on the MMCR, for up to 250range gates of radar data. (2)write C++ software to enable the root processor on the DSP card to (a) communicate with the host, both for radar control and data processing; (b) input data from the A/D or host with double-buffered DMA for a variable number of gates of variable length, for either uncoded or binary-phase coded pulses, for either single or dual polarization; (c) perform a variable number of coherent integrations on time series, if selected, with one of several filtering functions; and (d) receive averaged spectra from each of 4 parallel processors on the same DSP card, each for 1/4 the total number of range gates, and transfer them to the host. (3)write C++ software to enable 4 parallel processors on the DSP card to (a) receive processing instructions and data from the root processor; (b) process one set of gates while receiving another (double buffering); (c) perform cross-correlations in the case of pulse coding, for each range gate; (d) window data, calculate FFTs (single spectra), and produceaveraged spectra for each gate; and (e) communicate averaged and/or unaveraged spectra to the root processor. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures. This synopsis is issued for information only. No competitive solicitation is planned. No award will be made on the basis of requests in response to this notice. Information submitted in response to this notice will be used solely to determine whether or not use of competitive procedures to fulfill this requirement would be in the Government's best interest and must address qualifications pertinent to this requirement. The Government proposes to negotiate only with Radian International LLC because the new A/D, interface, and DSP cards and new software must be incorporated into Radian's proprietary POP4 software, to increase processor efficiency to at least 90%, by June 1999. The Government believes that Radian is the only responsible vendor that can respond to the above requirements within the time constraints of the project.
