摘　　要：针对射频隐身性能评估问题,提出了一种不依赖敌方探测设备的雷达射频隐身性能模糊评估方法。通过分析雷达辐射源在极化域、波形域、能量域中影响射频隐身性能的因素,构建极化域、能量域、波形域射频隐身指标,突破传统的"辐射-接收"模型的射频隐身评估方法,建立了基于机载雷达自身辐射信号工作状态和工作参数的射频隐身性能模糊评估方法。最后,对不同机载雷达系统进行仿真对比,结果表明该评估方法能正确反映机载雷达系统的射频隐身性能。In view of the RF stealth performance evaluation problems, this paper presents a method for fuzzy evaluating the RF stealth performance of the airborne radar system. Through analyzing the factors that radar radiation source influences the performance of the airborne radar system in the polarization domain, wave domain and energy domain, the RF stealth index of the waveform domain, polarization domain and the energy domain are constructed, a RF stealth evaluation method of the traditional ＂radiation reception＂ model is broken, the fuzzy evaluation method of radio frequency stealth based on the working state and working parameters of airborne radar system is established. Finally, the simulation evaluation of different airborne radar system is carried out. The results show that the method can correctly reflect the RF stealth performance of airborne radar system.
