摘　　要：本文研究了不可避免的阵元幅相误差对各列先微波合成为列子阵的矩形侧面相控阵机载预警（ＡＥＷ）雷达二维杂波谱的影响，并分析了基于理想＂脊背型＂杂波谱的二维信号处理性能下降的原因，为深入研究时空二维处理提供了基础．With microwave synthesizing employed to each column array,a rectangular planar phased arrays placed on airborne early warning (AEW) radars by side is transformed to a horizontal linear column subarrays along direction of platform flight.This paper study the effect of the elevation antenna pattern differences among column subarrays due to amplitude and phase errors existing in the array elements on clutter spoctra for AEW radars.
