In this paper, a novel synthetic aperture radar (SAR) two-dimensional (2-D) imaging algorithm which named CSMC is proposed based on compressed sensing (CS) and multi-channel (MC) SAR system. In particular, the algorithm operates in range and azimuth dimensions via CS technique, respectively. This new algorithm simultaneously provides a high resolution and wide-swath 2-D map of the spatial distribution of targets with a significant reduction in the number of data samples beyond the Nyquist theorem and with an implication in simplification of radar architecture. The simulation results show that this new imaging scheme presents many important applications and advantages which include higher resolution, less sampled data and higher noise immunity.
