| 摘 要： | 波动成像最关切的一步就是求取成像方程的系数矩阵，也就是雅可比系数矩阵，也即波场对物性参数的偏导数矩阵。从探地雷达波满足的有限元波动方程出发，推导得到随时间可变的雅可比系数矩阵满足的波动方程，并阐述了在时间域和频率域分别求解该雅可比系数矩阵的方法。

| Abstract: | The very important part for wave tomography is to get coefficentmatrix of tomography equations, that is the Jacobin matrix, or deviationderivative matrix of wave field to physical parameters. Basing on the radarwave finite element equations, the motion equations with which the Jacobincoefficiient Matrix are satisfied and introduced also the Jacobin matrix solvingmethod in time domain and frequency domain from such equations. |
