摘　　要：最近,Stanford大学EJCandes和DLDonoho教授提出了一种新的多尺度变换—Ridgelet变换,它特别适合于具有直线或超平面奇性的高维信号的描述,而且具有较高的逼近精度。将它应用于地震处理中,即可获得较以前其它方法无法达到的精度和效果。Recently, a new multiscale transform, called Ridgelet Tranform, is put forwarded by professor E J Candes and D J Donoho, This transform is especially suitable for the describing of those signals which have linear or super plane singularities and much better approximation. In this paper, we applied this method to seismic data processing and obtained much better results than that by other methods.
