Ground moving target imaging algorithm for single channel airborne CSSAR

摘要

Airborne circular stripmap synthetic aperture radar (CSSAR) has the advantages of short revisit time and large coverage, and thus is an attractive tool for wide area surveillance. A novel ground moving target imaging algorithm for single channel airborne CSSAR is proposed. The proposed algorithm can be implemented without knowing a target's motion parameters. Simulation results indicate that moving targets can be well focused by the proposed algorithm.
