Detection of Moving Targets Using Off-Grid Compressed Sensing

Detection of moving targets using M P ≈ 100 pulses from an airborne radar with multiple receive channels is a crucial point of Earth surveillance. Compressed sensing (CS) has been proven to be applicable to this problem in several publications. Nevertheless, the position of scatterers and the computational grid points for CS differ in general regardless of the scatterers' motion. Hence, we introduce in this paper a method for moving target detection using off-grid CS by reconstructing angle-Doppler diagrams.
