进行合成孔径雷达（SAR）成像仿真是研究成像雷达的一个重要手段。本文在分析SAR成像仿真机理的基础上,提出了一种利用视景仿真软件Vega进行SAR实时成像的仿真方法。利用软件平台VC＋＋、Multigen 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——RadarWorks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。
英文摘要：
Simulation of synthetic aperture radar （SAR） is an important means for studying the imaging radar. Based on the analysis of SAR＇ s imaging simulation principle, a method of SAR＇ s real-time imaging simulation is given with scene simulation software Vega. Based on software platform Visual C＋＋ creator Vega, 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.
