摘要

非正侧面阵机载雷达杂波谱与正侧面阵机载雷达杂波谱的主要区别在于它的杂波二维谱图随距离的变化而变化

杂波自由度相对增加

造成常规的统计型STAP杂波抑制方法不再适用.本文通过对非正侧面阵机载相控阵雷达杂波的分布进行详细的分析和研究

提出了一种基于CMT技术的非正侧面阵机载相控阵雷达杂波抑制方法.仿真结果表明了本文方法的有效性.

Abstract

The primary differences in airborne radar clutter spectrum between non-sidelooking and sidelooking arrays are that its Doppler frequency of the clutter spectrum varies with the range and its clutter DOF is increased

so that the conventional STAP methods are not feasible.In this paper

the clutter distribution of airborne radar with non-sidelooking arrays is analyzed and investigated in detail

then a new approach to airborne phased radar with non-sidelooking arrays based on CMT is presented.The simulation results verify the effectivity of the method.
