摘　　要：针对复杂战场空间对抗环境下射频传感器的射频隐身问题,开展基于复杂电磁环境的主动射频隐身方法研究。通过自身平台电子侦察设备感知敌方电磁信号分布特征,主动构建对己有利、对敌不利的复杂电磁环境,在敌方威胁侦察接收机的子信道内形成时频交叠信号,影响敌方电子侦察设备的信号检测和分选聚类处理,增加敌方侦察设备的测量误差,不能形成稳定的辐射源,降低信号的被截获概率。通过仿真分析可以看出:将复杂电磁环境当作干扰扰动信号,干信比在6 dB以上时,对侦察设备的频率、脉宽等参数测量和辐射源分选聚类影响较大。基于电磁态势感知结果主动构造的时频交叠的复杂电磁环境,可以根据作战任务和敌我双方电磁环境进行实时管控,实现主动射频隐身的优势。Aiming at the problem of RF stealth of RF sensors in complex battlefield space antagonism environments,the research on active RF stealth method based on complex electromagnetic environment is carried out.By perceiving the distribution characteristics of enemy electromagnetic signals through its own platform electronic reconnaissance equipment,it actively builds a complex electromagnetic environment that is beneficial to itself and unfavorable to the enemy,forms time-frequency overlapping signals in the sub-channel of the enemy threat reconnaissance receiver,affects the signal detection and sorting and clustering processing of enemy electronic reconnaissance equipment,increases the measurement error of enemy reconnaissance equipment,and cannot form a stable radiation source,and reduces the probability of the signal being intercepted.Through simulation analysis,it can be seen that when the complex electromagnetic environment is regarded as the interference disturbance signal,the interfering signal ratio is above 6 dB,which has a great influence on the measurement of frequency,pulse width and other parameters of reconnaissance equipment and the sorting and clustering of radiation sources.Based on the electromagnetic situation awareness results,the complex electromagnetic environment with overlapping time and frequency is actively constructed,which can be controlled in real time according to the combat mission and the electromagnetic environment of both the enemy and us,so as to realize the advantages of active RF stealth.
