Abstract :
In this paper a new ground moving target indication method based on multichannel synthetic aperture radar images is presented. The approach uses a variant of compressed sensing, enabling the analysis of off-grid velocities and consequently reducing velocity leakage. Results with experimental as well as simulated data illustrate the excellent velocity resolution of this technique.
