GR Attenuation by using Hankel SVD in F-X domain after applying different LMOs

An Explosion on the ground surface produces seismic waves, as these waves pass through the ground layers until being received by the geophone, Some noises are added to the seismic data. Usually SVD and Hankel Matrix are used to attenuate random noises from seismic data, and barely used in order to remove coherent noises. In this Paper our aim is to suggest a method in which by using LMO, groundroll waves are transformed to horizontalized coherent waves. By using Hankel Matrix, these waves can be distinguished and attenuated from the primary data. The outstanding difference of the suggested method compared to the previous techniques is that using the present algorithm the desired data can be saved considerably along by the attenuation of the noises simultaneously
