WIDE BAND HIGH FIDELITY DRFM (HIFID)

SPEC will develop a Wide Band High Fidelity Digital RF Memory designated the HiFiD. HiFiD supports generation of multiple high fidelity simulated targets for long range radar sensors and is innovative for future airborne target simulator applications. System provides high fidelity generation of multiple simultaneously delayed replicas of arbitrarily complex radar waveforms with very large instantaneous bandwidths (1-2 GHz). HiFiD will have 4 channels expandable to 16, each having an independently dynamic time delay and Doppler frequency offset. SPEC will develop the HiFiD prototype design favoring proven commercial off-the-shelf (COTS) technologies to minimize technical risk and achieve cost savings. Using existing SPEC DRFM technology, as a baseline, ensures cost effective, reduced risk HiFiD development. HiFiD development program uses existing process and analysis protocols to identify system components, develop technical specifications, and model/predict performance of the system identifying constraints/critical components. Existing computer/laboratory models support theoretical investigations to assess feasibility and practicality of the proposed system design. Leveraging existing DRFM technology significantly reduces HiFiD development technical risk and cost. Although this proposal leverages other DRFM technology, many differences in details of the HiFiD system as bandwidth, number of channels, maximum delay time, Doppler resolution and attenuation require significant innovation.
