Abstract

M035 Summary TOMOGRAPHIC INVERSION OF FOCUSING OPERATORS B.E. COX and D.J. VERSCHUUR Delft University of Technology Lab. of Acoustic Imaging and Sound Control PO Box 5046 2600 GA Delft The Netherlands The Common Focus Point (CFP) method has proven to be an appropriate tool for velocity model estimation. The CFP velocity estimation that is described in this paper is based on a separated inversion method in which first the focusing operators are updated with a data-driven procedure and after that the velocity model is estimated. The estimation of the propagation velocities and the focus point locations is done by one-way
