摘要

We study the efficiency of high-frequency acoustic sounding of small-size spatially localized inhomogeneities in shallow sea by a tomographic method. The method is based on that the focusing of the received and radiated fields to the region of the assumed location of the inhomogeneity is matched to the waveguide. During the observation, the statistical check is performed for hypotheses on the object location that are formed using a priori information on the waveguide model and data on the observation-system structure. To decrease the influence of the interference structure of the acoustic fields in the waveguide, we use accumulation of partial images corresponding to separate ray tomographic projections. Using a simulation model of the considered method, we analyze its accuracy and sensitivity under different observation conditions in shallow sea.
