N2 - In synthetic aperture radar (SAR) systems the antenna size needs to meet a minimum requirement in order for range and azimuth ambiguities to be avoided. This paper demonstrates that, by using random or jittered undersampling in the slow-time axis followed by sparse signal recovery techniques, one can reduce the SAR antenna size beyond that minimum requirement without significant loss target estimation performance. In other words, compressive sampling can enable compression of the physical interface in addition to the well cited benefits for data reduction.
