Attention has been devoted to multi-input-multi-output (MIMO) synthetic aperture radar (SAR) systems in recent years. The applications of MIMO-SAR systems that involve high-resolution wide-swath remote sensing, 3-D imaging, and multi-baseline interferometry are seriously limited by the ambiguous energy introduced by the imperfect orthogonal waveforms. The ambiguous energy degrades SAR image severely, because it can be accumulated from closely spaced scatters. In order to suppress the ambiguous… CONTINUE READING
