MIMO SAR Ground Moving Target Indication via Compressed Sensing

Synthetic aperture radar (SAR) systems are so popular in aerial imaging because of their high resolution. Ground moving target indication (GMTI) is one of the most challenging problems in this field. The use of multiple antennas in transmit and receive is an innovative idea that can overcome the limitations of SAR systems. In this paper, after modelling the received signal and focusing it, we propose an algorithm for GMTI with the use of compressed sensing. The proposed algorithm has low complexity compared to similar algorithms. Simulation results show that this approach is accurate in estimation of positions and velocities of moving targets.
