Synthetic Aperture Radar (SAR) operate by imaging a strip of ground that has potentially unlimited extent in its direction of motion, but is limited in the orthogonal range direction. Wide unambiguous swath coverage and high azimuth resolution pose contradictory requirements on the design of SAR systems. A promising technique to overcome this limitation is Digital Beam-Forming (DBF) on receive, where the receiving antenna is split into multiple sub-apertures. The received signals from each sub-aperture element can be separately amplified, down-converted, and digitized. Multiple beams can now be formed via post-processing and adaptive shapes. DBF techniques applied to SAR systems can suppress interference signals and spatially ambiguous signal returns from the ground and increase the receiving antenna gain without a reduction of the imaged area. To overcome the fundamental limitations of conventional SAR systems, IAI will develop the Scalable Architectures for Distributed Beam-Forming Synthetic Aperture Radar (DBSAR) tool. The DBSAR instrument will consist of wideband Transmitter-Receiver Modules (TRM) with lightweight, low power consuming, wideband frequency coverage, and waveform programmability. It will include synchronized multi-channel timing and reconfigurable algorithms that host the SAR processing, calibration and control routines.
