Separation of P- and SV-Wavefields from Multi-Component OBC Data in the Tau-P Domain

P002 SEPARATION OF P- AND SV-WAVEFIELDS FROM MULTI-COMPONENT OBC DATA IN THE TAU-P DOMAIN YANBIN WANG and SATISH C. SINGH Laboratoire de Géosciences Marines IPG Paris 4 Place Jussieu 75252 Paris cedex 05 France Abstract We present a scheme to separate P- andSV-wavefields from multi-component OBC data in the   ¡ £ domain. Based on the plane-wave components with known horizontal slowness the whole P- andSV-wavefields are separated into the direction of observed P- andSV-wave oscillation respectively by rotation of horizontal and vertical components. The incident P-andSV-waves are extracted from the separated wavefields by plane wave partitions at seabed. Parameters
