摘　　要：借助计算机仿真的方法,分析了目标信号从不同空间角度入射时,对弹载均匀圆形阵列天线测向角度分辨力的影响。仿真结果表明,对圆形阵列天线而言,分辨力受入射信号仰角的影响较大,而受方位角的影响较小。这可解释为信号能量分量影响了估计性能,其中仰角决定信号能量在阵列平面和阵列法线面的投影,方位角因阵列结构对称性使得各向估计精度差异不大。The influence of different target orientations on angle resolution based on the missile- borne uniform circular antennas were analyzed by computer simulation. The simulation results demonstrate that the angel resolution is strongly influenced by the elevation,and is almost irrelevant to azimuth. It can be theoretically explained from the perspectives of signal power projection.
