A novel digital beam-forming (DBF) method for multi-modes MIMO-SAR

Abstract

Multiple-input multiple-output SAR (MIMO-SAR) can transmit multiple waveforms and separate the radar echoes, which enables it to work in several modes simultaneously such as spotlight, sliding spotlight and strip-map modes. However, most of the existing waveforms are not well orthogonal, which cannot separate the echo completely and thus degrade the… (More)
