The process of formation and use of the spatial development of luminal parametric antenna in the marine environment

摘要

1. A method of forming and applying spatially developed luminal parametric array in a marine environment, comprising a restriction controlled waters emitting and receiving acoustic transducers, sound medium low frequency sonar signals stabilized frequency and forming therein working zones nonlinear interaction, and the parametric conversion waves luminal information and various physical nature, receiving the converted nonlinear waves and strengthening them in the band arametricheskogo conversion, transfer them to the frequency-time scale by a high-frequency region and narrowband spectral analysis, characterized in that the lumina receiving parametric antenna is formed as a multibeam, commensurate with the spatial extent of the marine environment controlled, for this purpose, omnidirectional radiating transducers which are arranged in the center of the water area, and place them on the underwater sound channel axis (PCO) above and below it, three receiving block is formed of three non-directional and kusticheskih converters each arranged in a vertical plane by triangles, and the depth of a similar emitting transducers at the vertices of triangles is directed towards the emitters, the nonlinearly transformed luminal signals multichannel receiving single converters three receiver units and by means of submarine cables via the switching unit and the switching signal analysis channels fed to the inputs of multichannel and multifunction reception path, wherein the measured
