Experimental Verification of Range-Dependent Inversion: Shallow Water Experiment 2006

Abstract

Modal dispersion data i.e. mode arrival time as a function of frequency have been used in inversion schemes that estimate sediment properties in a range-independent environment. This method has now been extended to include range-dependent environment. Simulation studies show that range-dependent sediment properties can be extracted if modal dispersion data are obtained for multiple source/receiver locations. It is proposed to collect suitable data during the Shallow Water 2006 experiment to verify the feasibility of estimating the range dependent sediment properties.
