ECOLOGICAL MONITORING OF UNDERWATER AREAS OF DIRECTED SOUND SOURES
The given papers purpose is analysis of interaction of acoustic fields lightings in multi-ray underwater waveguides with random anisotropic and local inhomogeneities of sound velocity fields (SVF). It is shown that when a receiving system containing of one vertical equidistant antenna array (VEAA) arbitrary chooses an aperture angle value of source it is impossible to determine presence of lenses in underwater waveguides (UW) against changing stochasticity of sound velocity fields (SVF). The possibility in principle to choose such aperture angle value of source system which enables to determine lenses presence in UW with one VEAA is proven in the paper.
