Research Institution
PRA proposes to develop a wideband adaptive digital beamforming solution to autonomously cancel multiple jammers at various locations, bandwidths, and center frequencies. The wide waveform bandwidths desired for fine range resolution in current and future phased-array systems impact the performance of adaptive cancellation algorithms due to the effects of wideband jammer dispersion, antenna architecture artifacts, and receiver channel mismatches across the band. Wideband adaptive algorithms must compensate for these effects to maximize SINR while preserving the desired compressed range response. The algorithm will be designed for efficient implementation on FPGA hardware. Performance of the algorithm will be evaluated using the Digital Array Radar Prototyping Simulation (DARPSim), a Matlab based tool developed by GTRI for modeling wideband phased-array antennas that utilize a digital beamforming (DBF) architecture.
