Pulse scattering from objects near an ocean surface and the inverse problem of target identification

摘要

We have developed the correct theory to describe scattering from targets near an interface. Pulse signals are particularly interesting because with proper placement of source and receiver it is possible to extract information about target depth and target characteristics from resonance properties. In this work we present the correct formulation of scattering from a target near an interface, and we present form functions and pulse return signals for spheroidal shells near an ocean surface or rigid bottom. Results for several cases are described.
