摘要

相控阵机载监视雷达的侧面阵在锥角一多卜勒频率域的杂波谱呈＂脊背型＂．据此可使时空二维信号处理大大简化，而杂波抑制性能仍可接近最佳。但是，在现有技术和工艺条件下，无线阵元和通道的误差不能忽略，从而引起＂脊背＂谱展宽并外渗，结果将使基于＂脊背＂谱结构的简化处理器的滤波性能下降，甚至失去二维处理的优越性，本文较详细地分析了性能下降的原因，并提出了改进方案。

Abstract

Angle-Doppler spectrum of clutter returns received by airborne surveillance radars based on a side phased array antennas appears as some kind of ridge. The simplified processor based on the "ridge"clutter spectrum suffers great performance degradation

in the presence of amplitude and phase errors between array elements. The reason for the performance degradation is analysed and a new modified 2-dimensional processor is proposed in this paper.
