Abstract

Synthetic Aperture Radar (SAR) is faced with complex electromagnetic environment in practical application, so it needs certain anti jamming ability. The SAR micro motion jamming can form false target string in the azimuth direction of SAR image, which makes it difficult to interpret SAR image. Therefore, based on the analysis of the principle of micro motion jamming, this paper proposes a SAR micro motion jamming discrimination method based on dual channel cancellation, and theoretically analyzes the feasibility of the algorithm. Finally, the effectiveness of the algorithm is verified by simulation.
