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 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, opposite each other as part of a cylindrical ring, a common multiplicative signal is formed with the received signal of the pressure gradient receiver together with the signals of the pressure gradient receivers 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 parallel oriented by the location of the axes of maximum sensitivity relative to the selected pair of piezoelectric prisms, followed by subtraction from the total multiplicative signal of its modulus in the form of the square root of the squared value of the total multiplicative signal to form the final unidirectional characteristic.
EFFECT: construction of the directivity characteristic of a vector receiver with a narrow beam opening with the possibility of rotation of the directivity characteristic.
