摘　　要：研究了有源诱偏系统中雷达与诱饵天线的空域极化特性。利用FEKO软件仿真得到了抛物面雷达天线和宽波束角锥喇叭诱饵天线的极化状态在不同空域指向上的分布,讨论了两种天线的空域极化特性在给定观测条件下的差异。仿真结果表明,在较大的观测区域下,诱饵天线的极化状态分布相对比较集中,而雷达天线的极化状态比较散乱。研究结果为反辐射导弹利用天线空域极化特性提高抗诱偏能力提供了理论依据和支持。The spatial polarization characteristics of radar antenna and the active decoy antenna in active decoying system were analyzed. The distribution of polarization state in different pointing space was obtained by FEKO, where the radar was a parabolic antenna and the de- coy was a pyramid horn antenna. The differences in spatial polarization characteristics of the two antennas were studied under different ob- servation conditions. The result indicates that the distribution of decoy＇ s polarization states is comparatively centralized near its desired po- larization, while the radar＇ s polarization states distribute dispersedly. The research of this paper provides a theoretical basis and support for the application of antenna＇ s spatial polarization characteristics to improve the performance of anti-radiation missile （ARM）.
