| 摘 要： | 对于含有激励误差的由子阵组成的平面阵列天线,本文推导了当子阵尺寸不同而且在子阵中采用行馈或列馈馈电方式时,波瓣的方差及主平面内峰值副瓣概率的计算公式,并在三种激励幅相误差的条件下,对主平面内峰值副瓣概率的理论值与统计值作了比较,结果相当一致。

| Abstract: | In this paper, the variance and the probability of eak sidelobe level for a planar array antenna with subarrays is studied. Different cases of row or column feeding structure with planar subarrays of various sizes are considered. The theoretical and statistical probabilities of the peak sidelobe level of the antenna patterns in principal planes for three kinds of excitation amplitude and phase errors are compared. |
