N-26 4C-SENSOR ORIENTATION USING MULTICOMPONENT-SVD METHOD APPLIED ON SHALLOW WATER DATA F. GLANGEAUD 1 J.L. MARI 2 and J. MEUNIER 3 Abstract 1 In shallow water wave propagation in the low frequency range gives rise to dispersive guided waves. In the presented field example the source signal is generated by air guns which are fired at regular distance interval along a profile. The receiver is a 4-component sensor laid on the sea bottom. SVD method applied on each 4C seismic trace is used to extract the strong dispersive guided wave. The orientation angles for each offset are also computed by
