  • In theory, the Ground Moving Target Indication (GMTI) method of space based sparse array Scanned Pattern Interferometric Radar (SPIR) only works when there are no ambiguities in azimuth. By decomposing the Point Spread Function (PSF) matrix, It is proposed that SPIR can work even there are a few ambiguities in azimuth, i.e. the ground scene can be recovered to some degree. Also through simulation experiments, SPIR is found to get much better GMTI performance than that of general space-time cascade processing.
