Along-track interferometric sar imaging based on distributed compressed sensing

For synthetic aperture radar (SAR), imaging based on compressed sensing (CS) can reconstruct the target scene with a reduced number of collected samples. But for a multi-channel along-track interferometric (ATI) SAR, the number of samples required could also be huge even though the CS processing is adopted. In this reported work, distributed compressed sensing (DCS) is introduced into ATI SAR. The ATI SAR based on DCS can achieve good performance and requires even fewer samples than that based on CS.
