Seismic wave field separation and denoising in linear domain via singular value decomposition（SVD）
Abstract：Due to the differences of propagation characteristics,apparent velocity and coherence in seismic signals,based on apparent velocities,the authors aligned target signals into those of best horizontal coherence by linear transform methods（such as NMO,linear moveout correction,etc.）.By means of singular value decomposition（SVD）,reconstructed signals by extracting the singular values of target signals.Then through inverse linear transforming,accomplished seismic wave field separation as well as noise attenuation afterwards.
