Geoacoustic inversion using vector acoustic modal dispersion: a sensitivity study

Geoacoustic inversion is traditionnaly performed using sound pressure data. In this paper, we present a sensitivity study of geoacoustic inversion using particle velocity, as recorded on a single vector sensor. The scope of the study is further restricted to shallow water and low-frequency impulsive sources. If propagating modes can be separated, then four vector acoustic metrics can be formed by coherent combination of pressure and velocity:...
