【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。更多还原

【Abstract】 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.更多还原
