Unambiguous Recovery of Multistatic SAR Data for Nonzero Cross Track Baseline Case

A wide-swath synthetic aperture radar (SAR) image is known to be achievable by merging multistatic aliased data that collected with an appropriate along-track displacement. However, in terms of both flexibility requirements like potentiality and cross-track (XT) interferometry design orbital safety, etc., a XT baseline not only demanded but also unavoidable. In this work, method proposed order merge SAR recover the Doppler spectrum unambiguously for nonzero case. The algorithm compared validated simulating azimuth invariant satellite constellation. results are promising dealing baselines.
