Free surface multiple removing via iterative prestack migration Introduction Y.-H. DE ROECK J.-M. COGNET G. CHAVENT F. CLEMENT IFREMER Acoustics and seismics group PO Box 70 F-29280 Plouzané France INRIA-Rocquencourt This study focuses on the suppression of the free-surface multiple in the framework of waveform inversion. No 1D assumption is made on the medium thus dipping events in the sea-bed can be represented with their true characteristics with regards to amplitude modulation versus the incident angle. The propagation model incorporates a specular reflection coefficient on the sea-bed that encompasses the local roughness of the first layer. However the model remains
