金属雨蚀头对天线辐射方向图的影响

摘要

The FEKO software based on method of moment（MoM） is used to achieve the accurate simulation of the electric property parameters of the single impulse antenna.By rotating the rain erosion protective metallic cap around the rotation axis of the antenna,it i%利用基于矩量法的FEKO软件对单脉冲天线电性能进行仿真分析,计算金属雨蚀头沿天线转动中心转动时单脉冲天线差方向图零深位置的偏移,揭示了金属雨蚀头对天线瞄准线误差的影响。
