摘要
目的研究线性插值射线追踪的新方法,提高追踪精度。方法在基本的线性插值射线追踪的基础上,对每一网格单元边界的周围结点进行上下左右交叉扫描。结果和结论本算法,在保留原有算法的优点的基础上,解决了基本算法中当发射点所在列有低速区时,与发射点同列的接收点的走时路径无法绕开该区域的缺点,提高了算法的精度。
Aim Study on new method of LTI for improve the precision of tracing, and improve the tracing precision. Methods On the basis of LTI algorithm, this methods adopts up-down and right-left algorithm to scan every gridding across. Results and Conclusion The results shows that this algorithm remain the virtue of LTI, and solve a neglect of LTI. The neglect in that if the transmitting spot and the receiving spot in the same row, and there a low-velocity area in this row then the tracing waves can not keeping away from this area. In addition, this algorithm is more precise than LTI.
