Lateral Pulse Wave Propagation in Lossy Weak Fluctuating Random Media: II. A Mutual Coherence Function

本文利用Born近似,并矢格林函数,富里埃变换和高频窄带近似等方法得到了耗散弱起伏随机介质中无线电通信相干侧面波脉冲传播的理论公式。瞬态相干侧面波脉冲波的互相关函数解析表达式亦被导出,数字计算表明,本文所得结果与前人的工作一致。

In weak fluctuating lossy random media, by using Born approximation, DGF method, Fourier transformation and high frequency narrow band approxi- mation, the theoretical formula for the coherent lateral pulse wave propagation in radio communication, is obtained in this paper. The analytical representation for mutual function for transient coherent lateral pulse wave is derived. Numeri- cal results reveal that the formulae in the paper agree with the previous theoreti- cal results.
