METHOD OF GENERATING A DIRECTIONAL CHARACTERISTIC OF A VECTOR-SCALAR MULTICOMPONENT RECEIVER Russian patent published in 2024 - IPC G01V1/18 

FIELD: hydroacoustics.

SUBSTANCE: invention relates to vector-scalar receivers and their use for hydroacoustic research, including for detecting sources of underwater noise in seas and oceans. Disclosed is a vector-scalar multicomponent receiver directional characteristic formation method, which consists in the fact that relative to two selected pairs of adjacent piezoelectric prisms with opposite polarization located perpendicular to axis of maximum sensitivity, which lie against each other, as part of a cylindrical ring, with the obtained pressure receiver total signal and the pressure gradient receiver signal, a common multiplicative signal is formed to form a final unidirectional directivity characteristic together with the pressure receiver and the pressure gradient receiver total signals from the other pairs of piezoelectric prisms with opposite polarization, symmetrically spaced apart on the sides of the cylindrical ring in variable segments from 0° to 180° and from 180° to 360° and parallel oriented by the axes of maximum sensitivity relative to two selected pairs of adjacent piezoelectric prisms with opposite polarization, lying opposite each other, in the composition of one half of the cylindrical ring, and other two selected pairs of adjacent piezoelectric prisms with opposite polarization, lying symmetrically in the other half of the cylindrical ring.

EFFECT: plotting the directivity characteristic of a vector-scalar receiver with a narrow beam opening with the possibility of rotating the directivity characteristic in a wide frequency range.
