FIELD: hydroacoustics.
SUBSTANCE: used to detect a moving sound source, measure the bearing to the sound source and the horizon of the sound source in shallow seas in a passive mode using acoustic combined receivers installed on the seabed, the coordinates of which and the angular position are considered known. An MN-channel block for generating a set of additional informative parameters for the combined process (C+P), an MN-channel block for generating a set of additional informative parameters for noise (N), an MN-channel block for averaging a complete set of 19 informative parameters are additionally introduced into the hydroacoustic complex for the combined process (C+P), MN-channel block for averaging the full set of 19 informative parameters for noise (N), MN-channel block for forming the signal-to-noise ratio (SNR) from the full set of informative parameters, MN-channel comparator operating on a full set of 19 informative parameters, an N-channel time-angular distribution shaping unit (TAD) in the local coordinate system associated with a combined receiver, operating on a full set of 19 informative parameters, an N-channel formation unit (TAD) in a geographic coordinate system, operating according to the full set of 19 informative parameters, the formation unit (TAD) of the hydroacoustic complex, operating on the full set of 19 informative parameters, the output of which is connected to the second input of the device for accessing digital data networks.
EFFECT: increasing the accuracy of determining the bearing to the sound source, as well as increasing the range of the complex in the sound source detection mode.
