非均匀环境下机载雷达STAP方法

STAP Methods for Airborne Radar in Nonhomogeneous Environment

空时自适应处理(STAP)是机载雷达信号处理中的一项关键技术,但其应用的实际杂波环境通常是非均匀的。本文对非均匀环境下各STAP方法进行了科学分类,并详细分析了各方法的内在机理及相互间的内在联系,同时总结评述了各方法的优缺点,最后指出了机载雷达非均匀STAP方法中有待于进一步研究和完善的相关问题。

Space-time adaptive processing（STAP） is a crucial technique for airborne radar signal processing.And it is generally applied in nonhomogeneous clutter environment.So the STAP methods suited in nonhomogeneous clutter environment are classified according to their essences.Then,the relationship and the basic principle of these methods are analyzed,and advantages and disadvantages of these methods are summarized.Finally,some frontiers and the related problems of these methods are also discussed.
