The software and hardware complex "ONTOMAP-V2" is designed for hydroacoustic calculations, simulation of the acoustic field for two-dimensional inhomogeneous medium conditions, assessment of anisotropic dynamic noise of the sea and reverberation interference, assessment of range of hydroacoustic means, formation and maintenance of the situation according to their data. The purpose of using the "ONTOMAP-V2" software complex in the Navy is to increase the efficiency of monitoring the underwater situation by hydroacoustic means of ships, submarines, helicopters and anti-submarine aircraft, anti-submarine observation centers and the use of marine underwater weapons.
