摘要
介绍了时间域拉东正反变换的基本原理及该项技术在地震数据处理中的应用。以Ng和Perz的算法为基础,以开发地震勘探处理与解释系统为实例,解决了实验中遇到的拉东正变换时收敛精度、反变换数据无损还原和截断信号引起的能量扩散、低信噪比情况下的滤波等问题,进一步研究了改进算法在其他地形下应用问题。
Based on a brief description of the basic principles of the time domain Radon transformation and inverse Radon transform,this paper studies the application of this technology to seismic data processing.Based on the algorithm designed by Ng and Perz in 2004 and the problems encountered in the seismic processing and interpretation system,this paper resolves the accuracy regarding the convergence precision of the time domain Radon transformation,the demand of non-destructive reduction,the energy spread problem caused by truncated signal and the signal＇s filtering problem under low S/N,and gives the applications of the improved algorithm in other terrains for further research.
