摘要
本文提出一种解析射线追踪法.将研究介质网格离散化,每单元的平方慢度为线性分布。由哈密顿函数法就可进行解析射线追踪和傍轴射线追踪.将这一方法与龙格—库塔法比较,说明这一方法是有效的.
We propose a technique for analytical solution of ray tracing in heterogeneous media. Complex heterogeneous media are divided into cells inside which the square of the slowness has a simple linear distribution. Tracing and paraxial ray tracing are performed analytically by a Hamiltonian formalism. It indicates that the analytical ray tracing method is efficent in comparison with Runge-Kutta method.
