Hydroacoustic location of underwater sound sources is commonly used to protect naval bases or military sea areas from various threats. Sonar technology applies hydrophones to detect sources of underwater noises. DOA estimation method based on the high angular resolution MUSIC algorithms are commonly used for small size antennas composed of hydrophones. The article proposes another approach to this problem. Additional equipage of the hydrophone with the GPS receiver and radio transreceiver enables construction of the distributed antenna. The size of such antenna can be significantly higher in comparison to the classical passive antenna. The article describes the algorithms of the sound sources location, results of the computer simulation and possibilities of hydrophone manufacturing as well its practical usage.
