摘要
针对复杂电磁环境下机载雷达与雷达告警接收机射频冲突问题,建立雷达辐射信号、天线隔离度和雷达告警接收机模型,详细分析雷达辐射信号对雷达告警接收机的干扰形成机理、干扰信号强度和干扰表现形式,并进行实例仿真。仿真结果表明机载雷达辐射信号对雷达告警接收机的干扰主要源自于雷达辐射主频信号,主频信号经空间耦合到雷达告警接收机超过其检测电平,造成雷达告警接收机产生虚假告警。
Aiming at the radio frequency conflict between airborne radar and radar warning receiver in complex electromagnetic environment,the radar radiation signal,antenna isolation and radar warning receiver model are established,and the interference mechanism,interference signal strength and interference form of radar radiation signal to radar warning receiver are analyzed in detail,and the examples are simulated.The simulation results show that the interference of airborne radar radiation signal to radar warning receiver mainly comes from the main frequency signal of radar radiation.The main frequency signal is spatially coupled to the radar warning receiver and exceeds its detection level,which is leading to false alarms.
