Sparse passive radar imaging based on direct broadcasting satellite

Direct broadcasting satellites (DBS) are located in geosynchronous orbit, and have the advantages of fixed system structure, broad beam coverage, and strong radiation power. Therefore, this paper studies the performance of DBS as the opportunity illuminators for passive radar. After establishing distributed passive radar imaging model based on DBS, we propose a sparse imaging method based on compressive sensing. Simulation results show the effectiveness of the new method.
