SONAR MODULE Russian patent published in 2016 - IPC G01S15/00 

FIELD: measurement.

SUBSTANCE: invention relates to measurement of fluid fields statistical characteristics and may be used for measurement of instantaneous values of hydrological characteristics in systems of underwater target location. Proposed device comprises array of sonar transducers (1), input amplifiers unit (2), switch (3), control and conversion unit (4), interface unit (10), connected to external processing and display device. At that, geophysical transducers and one hydroacoustic transducer are applied as sonar transducers (1). Control and conversion unit (4) comprises sampling-storage unit (5), control unit (6), digital-analogue converter (7), comparator (8) and reset signal generator (9). Interface unit (10) comprises receiver-demodulator (11) and transmitter-modulator (12).

EFFECT: technical result is high probability of detecting targets due to creation of combined (hydroacoustic and hydro physical) field of vision.
