Abstract :
A sparse image formation algorithm for VHF/UHF synthetic aperture radar that suppresses radio frequency interference is proposed. Unlike filtering based methods, the proposed algorithm does not introduce large range side lobes. The algorithm achieves this improved performance by leveraging the image sparsity.
