VERTICAL-SLICE OCEAN-ACOUSTIC TOMOGRAPHY - EXTENDING ABEL INVERSION TO NON-AXIAL SOURCES AND RECEIVERS

Le Journal de Physique Colloques, 1990
We discuss inversion of vertical-slice ocean-acoustic tomography (travel-time) measurements, in which we use the adiabatic-invariant approximation to convert multi-loop measurements to single-loop ray properties before using an Abel transform. We demonstrate the inversion by applying it to a simulated pulse-arrival sequence for a uniform sound channel ...
