MODELING ACOUSTIC TOMOGRAPHY OF OCEAN CURRENTS IN COASTAL REGIONS VIA WIDE-ANGLE PARABOLIC APPROXIMATION

摘要

Generalized Claerbout Parabolic Equation for Moving media (GCPE-M) ensures reciprocity and energy conservation of its solutions. The developed numerical scheme preserves these important properties in the finite-difference solution of GCPE-M. The presented model is applied to simulate full-field inversion of ocean currents in shallow sea under the presence of uncertainties in the sound speed field and bottom topography.
