摘要

提出了一种抑制机载相控阵雷达地杂波的时－空二维自适应处理新方法，将Ｃａｐｏｎ滤波法［３］作了修改，除待检测的多普勒通道输出的一组数据外，还将其左右相邻多普勒通道输出的另两组数据也加入进行自适应处理，本文将功率例置法推广应用于这三组数据，作时空二维处理，计算机模拟结果表明新方法比Ｃａｐｏｎ滤波法对阵元幅相误差具有更强的容差能力，对低速目标的检测性能有明显的改善。

Abstract

A new spatial-temporal adaptive processing

called Generalized Power Inversion（GPI）

is proposed to suppress ground clutter for airborne radars based on a side phased array antenna.First

a multi-channel Doppler filtering operation is carried out over the output data of each column subarray

then Generalized Power Inversion is applied to process the three Doppler output channels.Theoretical analysis and computer simulation results show that the GPI approach has tolerant ability in the presence of random amplitude and phase errors existing in the array elements.
