摘　　要：空时自适应处理(STAP)是一种有效的抗干扰技术,但其在非均匀环境下的性能将大大降低。介绍了STAP的基本工作原理,研究了基于频移的假目标干扰,利用假目标构造非均匀环境,从理论上分析了假目标干扰对STAP性能的影响,通过仿真验证了干扰效果。Space-time adaptive processing（STAP） is a kind of effective anti-jamming technology,but its performance will reduce greatly under the non-uniform environment.This paper introduces the fundamental principle of STAP,studies the false target jamming based on shift-frequency,uses the false target to construct the non-uniform environment,analyzes the influence of false target jamming on STAP performance from the theory aspect,validates the jamming effect through the simulation.

关 键 词：空时自适应处理 非均匀假目标 频移干扰
