An Iterative Method for Determining Seismic Wave Propagation Velocity

本文针对地震波传播速度的识别问题,提出了一种新的数值迭代方法,该方法是一种牛顿型迭代,并且每步迭代都利用吉洪诺夫正则化方法克服反问题的不适定性,因此,具有良好的数值稳定性,数值仿真实例说明了本方法的可行性及有效性.

In this paper, a new numerical iterative method is presented to identify the seismic wave propagation velocity. This method is a kind of Newton-type iteration, it overcomes the ill -posed of inverse problem by Tikhonov's regularization method in each iterative step. Therefore, the method has a good numerical stability. Numerical examples show that the method is feasible and effective.
