中文摘要
该项目开发了使用傅立叶技术计算合成地震图的方法。计算是针对弹性介质的,而不是更简单的声学假设。以前的工作已经表明,这种方法的计算速度是显式有限差分算法的3倍。该项目将验证该方法的准确性,对二维结构进行选定的建模工作,并将该方法应用于来自阿肯色州QUACHITA实验的PASSCAL数据。
英文摘要
Project develops methods for computing synthetic seismograms using Fourier techniques. Calculations are for eleastic media, not the more simple acoustic assumption. Previous work had shown that the methods can make a computation 3 times as fast as an explicit finite difference algorithm. Project will verify the veracity of the method, perform selected modelling efforts for 2-dimensional structures, and apply the method to PASSCAL data from the QUACHITA, Arkansas experiment.
