AUTOMATIC DETECTION AND CLASSIFICATION SYSTEM OF SHORT-RANGE SONAR Russian patent published in 2017 - IPC G01S15/00 

FIELD: physics.

SUBSTANCE: automatic detection and classification system of the short-range sonar contains a series-connected antenna, a reception-transmission switch, a receiver with a static fan of directional characteristics, a digital multichannel processor, a classification processor, a digital multichannel processing processor, a series-connected block for determining the correlation coefficient of consecutive time intervals, a block of selecting consecutive time intervals between spatial channels with a correlation coefficient greater than 0.5, a block of determining the amplitudes of the time samples, a maximum amplitude selecting unit with a correlation coefficient greater than 0.5, an identification unit for the total time with CC>05 and the formation of the object bank, the first output of the processor for multichannel processing is connected via the first input of the control unit and display with the radiation generator and the reception-transmission switch, and the second output with the second input of the control unit and the display.

EFFECT: system construction provides automatic detection of echo signals from objects under the influence of surface and bottom reverberation for one radiation cycle - reception for all spatial directional characteristics, automatic measurement of the parameters of the detected objects and the data output for their classification.
