The radiation patterns at different scan angle from - 20 to 20 degree are presented , and the angle difference between the maximum / minimum field points of their main beam shows the bse of the radome . at different frequencies , the radiation from the antenna has been discussed when azimuth scan angle ranges between - 20 degree and 20 degree . the relationship between 200 ~ 200范围内天线的和方向远区场、方位差方向远区场;得到方位瞄准误差、瞄准误差斜率和功率传输系数随扫描角和入射波频率的变化关系;并将所得数据与文献数据进行比较,表明间接射线法简单、有效且精度较高。
