【摘要】：针对采用均值类恒虚警检测方式的线性调频脉冲压缩雷达,本文提出间歇采样非均匀重复转发(ISNPR)实现多假目标压制干扰的方法.首先阐述了间歇采样转发干扰(ISRJ)产生多假目标的机理,同时对多假目标压制干扰的假目标参数进行了推导,包括假目标个数和信噪比.然后结合间歇采样重复转发干扰(ISPRJ)的数学原理,对间歇采样非均匀重复转发干扰(ISNPRJ)的多假目标压制效果进行了理论分析,并推导了干扰机参数如采样脉冲宽度、间歇采样周期、转发脉冲宽度以及发射功率的计算方法.最后对ISNPRJ的多假目标压制效果进行仿真验证,仿真结果表明该方法能够降低雷达对目标的检测概率,实现对雷达检测环节的有效压制.
[Abstract]:Aiming at the linear frequency modulation pulse compression radar using the mean CFAR detection method, In this paper, a method of intermittent sampling nonuniform repeat repeater (ISNPRP) is proposed to suppress multiple false targets. Firstly, the mechanism of ISRJs producing multiple false targets is described, and the parameters of multiple false targets are deduced. It includes the number of false targets and the signal-to-noise ratio (SNR). Then, combining with the mathematical principle of intermittent sampling repeat repeater jamming (ISPRJ), the suppression effect of ISNPRJs with intermittent sampling non-uniform repeater jamming is analyzed theoretically. The calculation methods of parameters such as sampling pulse width, intermittent sampling period, transmitting pulse width and transmitting power are deduced. Finally, the simulation results of multi-false target suppression effect of ISNPRJ are carried out. The simulation results show that this method can reduce the detection probability of radar target and achieve the effective suppression of radar detection link.
