摘要
空时自适应处理(STAP)已被证明是机载雷达在强杂波环境下检测目标的一种有效方法,但由于STAP处理的巨大运算量,使其在工程应用上变得极为困难。通常预警机的飞行高度在万米左右,大多数情况下地杂波为瑞利分布。文章讨论了一种针对杂波为瑞利分布情况下简化STAP算法的自适应处理,并通过对十六通道的信号处理的仿真来验证其性能。
The space-time adaptive processing had been proved to be an effective method of airborne early warning radar detecting targets in a complicated background,but because of huge computation,it is difficult to be applied in project application.Generally airborne early warning aircraft is flying at an altitude of thousands of meters,and its land clutter is Rayleigh distribution.This paper discusses an adaptive processing of simplified the space-time adaptive algorithm for Rayleigh clutter distribution,and to verify its properties through the simulation of the sixteen-channel signal processing.
