Detection of Spatially Localized Inhomogeneities in Refractive Waveguides when Probing with Focused High-Frequency Acoustic Pulses
We study the possibilities of tomographic observation of small-sized bodies in refractive oceanic waveguides within the framework of the ray description of the acoustic field. To increase the spatial resolution and sensitivity in solving the inverse observation problem, the waveguide-adapted focusing of the radiated and received pulses to the area of the assumed location of the observed body is used. To reduce the effect of the interference structure of the fields in the waveguide, we use the selection of individual ray tomographic projections followed by incoherent accumulation of partial solutions. A simulation model of the detection system using well-known physical models of the propagation and scattering of high-frequency acoustic waves is constructed.
