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 frequency modulation system and the conventional system to the performance of frequency measuring receiver are analysed. When radar signal is in linear frequency modulation system, the linear frequency modulation signal is used, with the appropriate time domain 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's survival.
