Abstract

This paper presents a multi-angle imaging system that integrates Multiple-Input Multiple-Output Synthetic Aperture Radar (MIMO-SAR) with the Multi-Angle Synthetic Aperture Radar (MA-SAR) in the context of spaceborne SAR's spotlight operation mode. The system addresses the issue of narrow swath coverage in traditional multi-angle imaging. It significantly relaxes the requirements on the pulse repetition frequency (PRF) compared to the Doppler bandwidth of the echo signal and achieves wide-swath imaging by resolving azimuth ambiguity. Simulation experiments demonstrate the successful integration of MIMO-SAR with multi-angle imaging, showcasing excellent imaging performance.
