本文应用传播函数矩阵的方法把Fuchs和Müller计算合成地震图的反射率法推广到层状不均匀介质中。在高频条件下,每层的基本矩阵用WKBJ渐近解表示,同时考虑到射线具有迴折点的情形。实例表明,这一算法是可行的,与原方法相比,在计算层状不均匀介质中的合成地震图方面可节省大量的计算机时。 In this paper, the method of propagation function matrix is ​​used to generalize the reflectivity method of synthetic seismograms computed by Fuchs and Müller into layered inhomogeneous media. At high frequencies, the basic matrix for each layer is represented by the WKBJ asymptotic solution, taking into account that the ray has a break back point. The examples show that this algorithm is feasible and can save a lot of computer time in the calculation of synthetic seismograms in layered inhomogeneous media compared with the original method.
