Simulation Technique of the Synthetic Aperture Radar

从SAR的回波模拟原理和实际需求出发,提出适合实际应用的基于真实SAR图像数据和方位时域回波生成方法的SAR回波数据模拟技术和半实物仿真方法。该方法能够获得真实可靠的回波数据,并实现对SAR和匹配处理系统的半实物仿真,对实现SAR系统的优化设计和快速测试具有重要意义。

Considering the simulation principle of SAR echo and practical requirement,this paper puts forward a simulation technique of SAR echoed data and a method of HWIL simulation based on the practical SAR image data and the method creating SAR echo in azimuth-time domain,which adapt to the practical application. This method can obtain reliable echoed data and realize the HWIL simulation for SAR and the matching processing system,which has great sense to realize the optimization design and fast test for the SAR system.
