对战机自卫干扰系统实施有源干扰（AECM）的射频隐身问题进行了研究。在侦察截获概率模型的基础上，讨论了AECM功率对战机射频隐身特性的影响，分析了有效干扰对AECM的功率需求，提出了一种基于预测雷达回波功率的干扰功率自适应控制方法，该方法结合当前接收到的雷达功率、本机RCS起伏以及不同干扰样式，使目标雷达接收机处回波信噪比保持恒定。通过计算机仿真，表明该方法在有效干扰的同时能够降低敌方侦察系统截获干扰信号的概率，从而提高战机的射频隐身能力。

The Radio Frequency (RF)stealth character of airborne Active Electronic Counter Measure (AECM)is studied. The influence of the AECM power on airplane’s RF stealth character is analyzed based on the model of intercept probability of Electronic Counter Measures(ESM). In order to make the radar receiver’s echo signal-to-noise (SNR)remains constant,an adaptive method of AECM power controlling by forecasting the radar received power is put forward. Computer simulation indicates that this method,compare to the conventional way,combines the received radar power,RCS blinking and the type of jamming could destroy the radar work effectively and improve the stealth performance of AECM as well.
