Abstract: An imaging method of multi-direction swath based on space-born hybrid phased-MIMO SAR is proposed, which combines traditional phased-array radar with a new technique for multiple-input multiple-output (MIMO) radar, and the 2-D DBF for this system is presented to achieve unambiguous wide swath imaging with high azimuth resolution. Firstly, the signal model was built and the virtual control matrix of the Hybrid Phased-MIMO SAR was derived. Secondly, considering the image overlap and range ambiguity caused by multiple direction imaging, the adaptive Digital Beamforming (DBF) algorithm in range was proposed to separate the overlap area in images and to suppress the ambiguity. Finally, azimuth ambiguity that exceeds the signal bandwidth is suppressed by weighting in azimuth. Simulation results validate the effectiveness of this 2-D processing. Compared with space-born bi-direction SAR by two major lobes and multi-direction SAR by phased array, operation mode will be more flexible by using our method, and satisfy requests of multifunctional space-born SAR.

Key words: information processing, space-born phased-MIMO SAR, signal model, 2-D BDF, image overlap, image ambiguity
