Implementation and Validation of SCORE Digital-Beamforming and Staggered SAR Interpolation on a FPGA Platform

Kurzfassung

Multi-Channel SAR systems utilizing digital beam forming (DBF) allow for higher resolutions and wider swaths than Single-Channel SAR systems, but require more complicated on-board processing. Two multi-channel SAR techniques, Scan-On-Receive and Staggered SAR are investigated in this paper. We present the implementation of Multi-Beam SCORE and Staggered-SAR postprocessing on a novel, multi-FPGA ground demonstration platform. We utilize specifically designed input signals to verify error-free computation and validate simulation results
