Image Simulation in SAR Based on Creator/Vega

合成孔径雷达(SAR)成像以飞机或卫星为平台,且以全天候,全天时,可全透性等优点获取高分辨率图像,已经成为国内外研究热点,特别在军事领域有着广泛的应用前景。论文研究了合成孔径雷达成像仿真原理以及其成像仿真系统框架结构,以及地形场景模型的构建与RCS材质映射,最后通过Vega中的RadarWorks模块来模拟合成孔径雷达成像仿真,通过设置合理的参数,能够较好的仿真出真实的合成孔径雷达图像。

Synthetic Aperture Radar （SAR） imaging based on aircraft or satellite platform, can obtain high resolution images through features such as with all-weather, all-time, full-permeable, which has become the research focus of world, especially in the military field. In this paper, synthetic aperture radar imaging principle and its imaging simulation system framework, as well as terrain scene model RCS＇s construction and material mapping are studied, and finally the RadarWorks of Vega modules is used to simulate synthetic aperture radar imaging simulation, and by setting reasonable parameters, bet ter simulation of real synthetic aperture radar images can be achieved.
