Research on mechanism of near carrier frequency FM noise for CW guided air-to-air missile weapon system

分析并建立了有规则干扰、飞机电源、连续波照射器高压纹波、连续波照射信号及其近载频噪声有关的数学模型 ,从系统角度对机载环境下导弹武器系统射频近载频调频噪声的产生机理进行了研究。通过建立近载频调频干扰和内部相干谱线共同调制时导引头回波信号的数学表达式 。

The mathematical models are established and analyzed including regular interference, airplane power supply, CW irradiator high voltage ripple, CW irradiation signal and near carrier frequency noise. The mechanism of near carrier frequency FM noise for airborne weapon system is studied. With the establishment of expressions of seeker's returning wave when co modulating the near carrier frequency FM interference and the inner coherent signal, the interference mechanism of near carrier frequency FM spectrum to the seeker acquisition device is studied.
