低截获波形作为实现机载雷达射频隐身性能的重要技术手段,评估其射频隐身能力变得愈加重要.为了避免单一指标的片面性以及贴合实际作战的考虑,提出了一种基于发射方的机载雷达低截获波形射频隐身性能定量评估方法.从信号波形本身的性质和辐射过程中射频隐身性能出发,通过相对熵和波形截获因子的加权,构建出波形射频隐身表征因子.最后,利用该评估方法对4种机载低截获波形进行了仿真实验,结果表明,该方法对于机载雷达低截获波形的射频隐身性能具有很好的度量作用.%Low intercept waveform as the important technical method to realize the RF stealth of airborne radars,it's RF stealth capability becomes even more important. In order to avoid the single index respectively and realistic consideration,an airborne radar waveform RF stealth performance quantitative evaluation method which based on the emission is proposed. From the nature of the signal itself and the RF stealth performance in the process of radiation,waveform RF stealth characterization factor,which through the weighted relative entropy and waveform intercept factor,is constructed. Simulation is carried out during which 4 genres of low interception probability waveforms are evaluated by our method,which shows that the method is a good measure of the RF stealth performances of low interception probability waveforms of airborne radars.
