摘　　要：文中研究了一种单脉冲跟踪雷达抗距离欺骗干扰的新方法.在高速可编程 DSP(数字信号处理)芯片所构成的距离跟踪系统中,作者通过对接收机 AGC 电压和距离波门移动速度的实时测量,构造了干扰的判别函数并实现对干扰的判别与对抗.实验结果表明,该方法克服了常规抗距离欺骗干扰方法的不足,具有判扰准确和抗扰跟踪精度高的特点.A novel method for a mono-pulse radar to counter the range cheat jamming is proposed.Based on the measurement of the AGC voltage and the moving velocity of the range gate,a decision function is constructed to decide the existence of the jamming,and a memory tracking approach is adopted to counter the jamming.Experimental results show that the method overcomes the shortcomings of conventional methods for countering the jamming,and has a high decision accuracy of the jamming and a high precision of memory tracking.
