利用软件平台VC＋＋、Muhigen Creator和Vega设计机载合成孔径雷达（SAR）成像仿真系统，分析了影响机载SAR成像质量的各种参数，论述了利用Vega的雷达仿真模块——Radar Works开发机载SAR成像仿真软件的流程以及整体系统的实现等关键技术。仿真结果表明，该系统能较好地模拟各种参数下机载SAR的成像效果，对机载SAR成像系统性能评估有一定的辅助作用。

Based on software platform Visual C -Creatorvega,an airborne SAR imaging simulation system is designed.Various parameters that have influences on the imaging quality of airborne SAR are analyzed.A series of key techniques are discussed such as the development flow of airborne SAR imaging simulation software by Vega radar simulation module-radarworks and the implementation of the whole system.The simulation results show that this simulation system can realistically simulate the performance of SAR imaging systems.
