阵列天线口径幅相误差分析

Aperture amplitude and phase error analysis of the antenna array

对Ｔａｙｌｏｒ，Ｄｏｌｐｈ－Ｃｈｅｂｙｓｈｅｖ和Ｈａｒｍｉｎｇ口径分布分别进行了误差模拟计算，分析了口径幅相误差对天线远场方向图的影响，给出了实现超低副瓣性能的容差范围．

The errors of aperture distributions of Taylor Chebyshev and Harming are simulated respectively. The effects of the aperture amplitude and the phase error on the antenna farfield pattern are analzed, and the allowance ranges for realizing ultralow side lobe performance are given.
