Noise Rejection by Multicomponent SVD-Wiener Joint Filters

P017 NOISE REJECTION BY MULTICOMPONENT SVD-WIENER JOINT FILTERS Abstract 1 In case of highly corrupted VSP dataset we propose to estimate the noise field in sequence using jointly multicomponent SVD and Wiener filter. Multicomponent SVD working on 3C Components merged into a special way allows us to increase the size of the noise space and to take into account in the same time all the physical properties existing in the 3C. Resulting a better noise extraction than classical SVD. The SVD noise field model thus obtained is used as reference for a Wiener filter in order to estimate accurately the
