机载航电系统射频隐身性能多域联合评估方法

针对机载航电系统自身辐射源特性，提出一种不依赖敌方探测设备的机载航电系统射频隐身性能评估方法。分析机载航电系统设备在极化域、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，打破常规的 “辐射-接收”模型的隐身性能评估方法，建立基于机载航电系统自身辐射信号工作状态和工作参数的射频隐身定量评估方法。对机载雷达系统进行仿真评估，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。
According to the characteristics of the airborne avionics system, a method for evaluating the RF(radio frequency) stealth performance of the airborne avionics system was presented. The factors that influence the performance of the airborne avionics system in the polarization domain, wave domain and energy domain were analyzed, the RF stealth index of the waveform domain, polarization domain and the energy domain were constructed, an RF stealth evaluation method of the traditional “radiation reception” model was broken. And a quantitative evaluation method of radio frequency stealth based on the working state and working parameters of airborne avionics system was established. Finally, a simulation evaluation of airborne radar system was carried out. Results show that the proposed method can correctly reflect the RF stealth performance of airborne radar system.
