摘要
本文通过在雷达干扰信号处理领域中应用随机微分,系统地对噪声调频干扰信号进行了分析。首先建立了噪声调频干扰信号通过脉冲压缩雷达中频滤波器后所满足的福克尔-普朗克方程,再通过群移傅立叶变换(Motion-Group Fourier Transform,MGFT)对偏微分方程组进行了转换,将其转化成了变系数齐次线性微分方程组,结合Peano-Baker级数法得到了该方程组的解,并得到了其概率密度函数。
With the stochastic differential in radar jamming signal processing, the noise frequency modulation signal was particularly analyzed in this paper. The Fokker-Planck equation, which is used to describe the processing of noise frequency modulation signal, was presented. According to the Motion-Group Fourier Transform, the partial differential equation was converted into the variable coefficient homogenous linear differential equations. With the Peano-Baker series, the solutions and the probability density function of noise frequency modulation were given.
