The combination of space-time waveform encoding and digital beamforming (DBF) has been proposed as a novel concept to improve the performance of synthetic aperture radar (SAR) systems in the future. In this paper, we research one such new operational mode to reduce azimuth ambiguity in high-resolution wide-swath SAR image and present the processing scheme based on 2-D DBF for this mode. The main procedures and techniques are described in detail, and a complete mathematical derivation of the… CONTINUE READING
