摘要
选用GRASP(General Reflector Antenna Software Package)软件计算雷达天线反射面随机多穿孔对雷达天线增益和跟踪相位两个参数的影响。结果表明:天线增益下降60%以上,雷达天线将无法满足对低轨卫星进行数据收发要求,天线相位偏移55°以上,无法满足天线自跟踪要求,当穿孔(面积127 mm×127 mm)数量超过200个后,雷达天线增益和跟踪相位将发生剧烈变化,无法完成低轨目标跟踪测量任务。
The general reflector antenna software package(GRASP)was utilized to simulate the effects of randomly distributed multiple perforations on antenna gain and tracking phase parameters.The results indicated that if the antenna gain decreased by more than 60%,the radar antenna would fail to meet the requirements for data transmission and reception with LEO satellites.When the phase offset exceeded 55°,the antenna was incapable of fulfilling its self-tracking requirements.When the number of perforations(size 127 mm×127 mm)exceeded 200,the radar antenna's gain and tracking phase would undergo drastic changes,rendering it unable to perform LEO target tracking and measurement missions.
