| Abstract: | 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. |
