Multi-time Snapshot based Off-Grid DOA Estimation of Sparse Array Antennas using MFOCUSS Algorithm

An off the grid direction-of-arrival estimation of the signals originating from quasi static targets is suggested in this paper using compressive sensing based sparse reconstruction of multiple time snapshot MFOCUSS algorithm. Simulation outcomes show that multi-snapshot restoration of the target location gives more accurate results in terms of root-mean-square error with respect to single snapshot instance.
