基于示样脉冲循环转发的空时自适应处理干扰研究

Study of Space-time Adaptive Processing Jamming Based on Sample Pulse Repeated Transmitting

研究了示样脉冲循环转发干扰对空时自适应处理(STAP)的干扰效果,分析了STAP技术的原理,建立了示样脉冲循环转发干扰的模型,论述了示样脉冲循环转发的干扰效果。仿真结果表明:STAP可以提取被强地杂波背景淹没的目标,而采用示样脉冲循环转发干扰时,STAP无法对目标信息进行正确的提取,干扰效果非常明显。

This paper studies the jamming effect of sample pulse repeated transmitting jamming on space-time adaptive processing （STAP）,analyzes the principle of STAP technique, establishes the model of sample pulse repeated transmitting jamming （SPRTJ）, discusses the effect of sample pulse repeated transmitting jamming. The simulation results show that the target covered by strong ground clutters can be extracted through STAP, but the STAP target information can＇t be extracted correctly through the STAP when SPRTJ is used,so the jamming effect is very obvious.
