本文对经过连续分层介质传播的射线理论方法给出两个贡献。其一是给出以样条多项式对声速剖面作平滑近似的方法,其二是消除了在常用的距离积分中出现的奇性,从而得到了用于求解各种声传播问题的自动数值程序。
In this paper, we give two contributions to the ray theory method of continuous layered media propagation. One is to give a smooth approximation to the velocity profile with a spline polynomial, and the other is to eliminate the singularities that occur in the usual distance integrals. An automatic numerical procedure for solving a variety of acoustic propagation problems is thus obtained.
