沙丘鸣震是由于地震波在沙层中多次反射所产生的一种层间多次波 ,这是在陆上资料处理中经常遇到的现象。它的存在使地震剖面的分辨率降低 ,并干扰人们对有效波的认识。主要介绍了在Omega地震资料处理系统中用Radon变换消除沙丘鸣震的原理和方法。该方法实质上是一种“减去波”方法 :首先在τ -p域中把想要去除的相干干扰信号 (包括多次波 )识别并分离出来 ,然后再转换到t-x域并将它从原始的地震信号中减去。对陆上某工区实际资料的实际处理结果表明 ,用Radon变换消除沙丘鸣震取得了较理想的效果 Sand dune ringing is a type of inter-layer multiples produced by the multiple reflection of seismic waves in sand layers, a phenomenon often encountered in onshore data processing. Its existence degrades the resolution of seismic sections and disrupts people’s knowledge of effective waves. This paper mainly introduces the principle and method of using Radon transform to eliminate sand dune ringing in Omega seismic data processing system. The method is essentially a “subtractive wave” approach: the coherent interfering signal (including multiples) to be removed is first identified and separated in the τ-p domain and then converted to the tx domain and shifted from Subtract the original seismic signal. The actual processing results of the actual data in a certain land area on the land show that the Radon transform is used to eliminate the dune mound and achieve a satisfactory result
