摘要

论文研究了距离模糊条件下双基地STAP的距离独立性补偿问题

首先建立了此背景下的杂波模型

比较了双基地无模糊距离和有模糊距离情况下的不同点

指出了现有估计方法在含模糊距离的双基地杂波协方差估计问题中存在的不足;其次

在具体分析各距离门的杂波分布特点的基础上提出了基于数据分离的杂波协方差矩阵估计方法

给出了该方法的数据处理结构和实现步骤;最后

通过数值仿真比较了该方法与基于映射的距离独立性补偿方法的处理性能

结果表明该方法具有更好的信噪比改善性能.

Abstract

Range-dependence compensation for bistatic STAP on the condition of range ambiguity was studied.Firstly a clutter model for this background was built

the difference between range ambiguity and no range ambiguity was analyzed

and the existing bistatic STAP range-dependence compensation method's deficiency was pointed.Secondly a new method named range-dependence compensation based on data separation was proposed according to the different range gates' clutter character analyses.At last data simulation shows that the new method's signal-to-noise upgrading performance is better than the RBRDC's.
