In the proposed approach, basis vectors corresponding to on-grid point reflectors are perturbed on a finer grid to find the appropriate bases for the reconstruction of off-grid targets. To provide efficiency of the reconstruction, the EMMP algorithm is applied to find reflectivity center locations. As demonstrated by simulations, the proposed approach significantly improves the performance of sparse SAR image reconstruction. © 2013 IEEE.EnglishBasis vectorCenter locationsOff-gridsPoint reflectorSAR ImagesAlgorithmsImage reconstructionReflectionSynthetic aperture radarConference Paper10.1109/RADAR.2013.6586034
