摘　　要：介绍了ELINT系统的信道化接收机的相关特性,讨论了己方雷达信号分别为线性调频体制及常规体制时,不同的干扰信号对接收机测频性能的影响:当雷达信号为线性调频体制时,采用线性调频干扰信号,满足合适的时序关系,使得接收机测出的信号带宽展宽;当雷达信号为常规体制时,干扰信号为线性调频或频率捷变体制,使得接收机对雷达体制判断错误。通过仿真验证了干扰效果,保护了己方雷达信号的技术参数不被正确获取,从而进一步提高了雷达的生存性能。This paper analyzed the related properties of channelized receiver, the interference of different signals in either linear fre-quency modulation system and the conventional system to the performance of frequency measuring receiver are analysed.When ra-dar signal is in linear frequency modulation system, the linear frequency modulation signal is used, with the appropriate time do-main configuration, making the receiver to measure the bandwidth of the signal is broadening;when radar signal is in conventional system, the chirp signal or cheat pulse is used, making the information of the radar system wrong , then achieving the purpose of deceptive jamming.Jamming effectiveness is verified by simulation and their technical parameters of radar signal are protected, so as to further improve the performance of radar＆#39;s survival.
