摘　　要：针对雷达抗干扰性能分析的需求,论文在研究噪声调频干扰的特点、以及宽限窄电路抗噪声调频干扰原理的基础上,推导了采用宽限窄电路抗干扰措施后,相对于常规脉冲压缩体制雷达的抗干扰得益计算公式。该公式综合考虑了宽限窄电路中宽、窄滤波器带宽设置、限幅器的限幅电平设置,以及后续级联的脉冲压缩部分的增益损失等多种因素,并通过仿真进行了测试,验证了该公式的合理性,可以作为雷达抗噪声调频干扰性能分析及评估的一种方法。According to the requirement of radar anti-jamming performance analysis,based on the study of the characteristics of noise frequency modulation jamming and the principle of WBDF circuit anti-jamming,this paper deduces the calculation formula of anti-jamming benefit of WBDF circuit anti-jamming compared with conventional pulse compression radar.The formula compre⁃hensively consideres the wide and narrow filter bandwidth settings,limiter limiting level settings,and gain loss of the subsequent cascaded pulse compression in the WBDF circuit.The rationality of the formula is verified by simulation test,which can be used as a method for analyzing and evaluating radar anting noise FM jamming performance.
