| 摘 要： | 对于在时频域上分散的噪声信号,很难在传统的频率-波数(f-k)平面上找到单一的合适的滤波区域.基于S变换的空间-频率-波数(x-f-k)变换(SXFK)是一种依据偏移距变换的f-k域滤波,能很好地解决该问题.然而,SXFK变换是基于S变换的固定的基本小波,使其在应用中会受到限制.提出基于广义S变换的x-f-k变换(GS...

| Abstract: | If the noise signals were highly scattered,it would be difficult to define a simple and proper filtering zone in f-k domain.The filtering method based on the x-f-k transform was a f-k filtering based on defining the offset-varying velocity filter at different offsets separately,it could be used to solve the problem well.However,by using the fixed basic wavelet of S transform,SXFK transform was a basic wavelet based on S transform,it was limited in application.In this paper,the x-f-k transform based on the g... |
