The distributed SAR reconstruction method for line target

Abstract

Due to the limited radar motion track, the main lobe information of the line target in the scene is often not observed by the SAR, resulting in discontinuity of the line image and reducing the quality of SAR image. In this paper, the line target reconstruction method based on the sparse distributed SAR system is proposed. We analyze the relationship between the SAR imaging performance and radar parameters of the sparse distributed SAR system, and estimate the geometric parameters of line targets in the scene, then reconstructed the continuous line images to improve image quality. Finally, the simulation of the proposed method is carried out.
