FIELD: radio engineering, communication.
SUBSTANCE: receiver includes two orthogonally oriented circular sensing elements, provided with variable-diameter nozzles mounted orthogonally one after the other on the axis of the cylindrical body from the sound-reflecting material. Coaxially sensitive elements on the longitudinal axis of the body have two orthogonally oriented accelerometers. Sensitive elements and their corresponding accelerometers through amplifiers are connected to a subtracting device for measuring the pressure gradient. When measuring the pressure gradient, the gain factors are pre-tuned.
EFFECT: increasing the noise immunity and reliability of pressure gradient measurement.
