A Fast SAR Raw Data Simulator for Extended Scenes Using Block Clipping Method

Published: 29 October 2022 Publication History

Abstract

With the improvement of SAR observation swath and image resolution, the computational complexity of SAR raw data simulation increases greatly, which challenges the engineering application of SAR simulation technology. To improve the simulation efficiency of SAR raw data, a block clipping method is proposed in this paper, which can remove the targets not illuminated by the radar beam in the scene with little computation. The range frequency-domain pulse coherence (RFPC) algorithm is widely used for SAR raw data simulation in the engineering field. The Block clipping algorithm can be combined with the RFPC algorithm to improve the simulation efficiency of the extended scene. The experimental results show that when the number of targets in the simulation scene is 6000×6000, the simulation efficiency of the RFPC algorithm is improved by 2-3 times after using block clipping technology.
