摘要
针对偏馈形式的移动波束天线,分析了波束指向和双轴转角的换算关系,二次开发了反射面天线仿真计算软件GRASP8SE,最后对天线在波束扫描状态下的电性能进行了仿真计算,并和实测结果做了对比。
An offset Gregorian mobile antenna is analysed by deducing the relationship between the beam orientation and the dual axis driven angle. Benefitting from GRASP8 Student Edition, which provides a free, open antenna simulation module, an analytic tool specially for steerable antenna is developed by VC＋＋ and MATLAB and produces good results in accordance with actual patterns.
