The 3DSVD-modified, a way to ensure waves denoising and separation

The use of Multicomponent sensor arrays permits take into account the specific structure of recorded signals, providing thus a substantial improvement of seismic data acquisition/processing systems. In this paper, we present a modified 3DSVD technique as an extension of the SVD-modified one. The proposed method improves the classical 3DSVD results by eliminating the noise rests in the signal subspace. Tests on synthetic 3D seismic data were realized and the obtained results are satisfactory which confirm the validity of the proposed processing.
