摘　　要：为解决合成孔径雷达(SAR)仿真过程未充分考虑平台运动过程中的电磁参数实时变化对回波生成过程的影响,生成的回波往往不具有通用性的问题。论文提出一种基于雷达平台运动特性、目标及环境特性实时解算雷达系统电磁特性的SAR回波生成系统。并对某机场进行建模成像对该回波生成系统进行验证,结果表明,论文提出的系统具有较好的成像性能。In order to solve the problem that the impact of the real-time changes in electromagnetic parameters during the movement of the platform is not considered in the SAR echo generation procedure,which leads that the SAR echo results are not universal. A SAR real-time simulation platform based SAR echo generation system is proposed,the system is fully considered the movement of the radar platform and the objectives and environment characteristics,which is used to the real-time electromagnetic properties in SAR echo generation procedure. The result shows that the proposed SAR real-time simulation platform based SAR echo generation system has good imaging performance.
