METHOD FOR FORMING A UNIDIRECTIONAL CHARACTERISTIC OF A VECTOR-SCALAR MULTICOMPONENT RECEIVER Russian patent published in 2023 - IPC G01V1/18 

FIELD: hydroacoustics.

SUBSTANCE: vector-scalar receivers and their use for hydroacoustic research, including the detection of sources of underwater noise in the seas and oceans. A method for forming a unidirectional characteristic of the detection path of a vector-scalar multicomponent receiver is claimed, which consists in the fact that, relative to the maximum sensitivity axis of a selected pair of piezoelectric prisms with opposite polarization located on the axis of maximum sensitivity, opposite each other as part of a cylindrical ring, with the resulting total signal of the pressure receiver and the signal of the receiver pressure gradient, a common multiplicative signal is formed to form the final unidirectional characteristic together with the total signals of the pressure receiver and the pressure gradient receiver from the remaining pairs of piezoelectric prisms with opposite polarization, symmetrically spaced from each other along the sides of the cylindrical ring in variable segments from 0° up to 180° and from 180° up to 360° and oriented parallel to the location of the axes of maximum sensitivity relative to the chosen pair of piezoelectric prisms.

EFFECT: construction of the directivity characteristic of a vector-scalar receiver with a narrow beam opening with the possibility of rotation of the directivity characteristic.
