摘要

本文提出了一种机载预警侧面相控阵雷达抑制地杂波的时-空二维自适应方法

该方法先对各列子阵的数据作多通道的多卜勒滤波

然后分别对相同多卜勒滤波器输出的数据作Capon自适应处理。理论分析和计算机模拟结果表明

本文方法的杂波抑制性能在天线阵元存在一定的随机幅度和相位误差情况下损失不大

对阵元失效也不敏感。

Abstract

In this paper

a 2-D temproal-spatial adaptive technique is proposed to suppress ground clutter for early warning radars based on a side phased array antenna.First

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

then Capon’s adaptive beamforming technique is applied respectively to process the output corresponding to the same Doppler filter.Theoretical analysis and computer simulation results show that the performance suffers little form the proposed approach degration in the presence of large random amplitude and phase errors existing in the array elements.In addition

it is not sensitive to the element failure.
