利用特征积分法求解二维波动反问题的速度参数
Solving the Velocity Parameter of the 2-D Wave Inverse Problems with the Integration-Characteristic Method
-
摘要: 对于从地震波勘探中引出的一类二维波动反问题,本文应用特征法,首次给出一个新的求解速度参数的算法,并用理论模型试算,得到较满意的结果.Abstract: For the 2-D wave inverse problems introduced from geophysical exploration, in this paper, the author presents integration-characteristic method to solve the velocity parameter, and then applies it to common shotpoint model data, in noise-free case. The accuracy is quite good.
