摘　　要：现代干扰机能通过侦察识别雷达发射信号参数,并调制转发以实现对相参雷达的干扰。为有效对抗敌方侦察,针对上述方式,提出了随机变T+2脉冲MTI再级联滑窗(非相参)检测的抗干扰方法。该方法较全相参工作时性能略有下降,但提升了雷达在复合相关干扰背景下的工作性能,仿真结果证明了该方法的有效性。Coherent radar is jammed through modulating and repeating the radar signals based on detecting and recognizing radar signal parameter. To confront the enemy reconnaissance effec-tively, a method of two pulses MTI cascade sliding window （non-coherent） detection is put for-ward. Compared to full coherent work, the radar performance of this method is declined, but it can work under the background of composite coherent jamming. Theoretical analysis and simula-tion results demonstrate the effectiveness and universality of this method.
