UNDERWATER ENVIRONMENT ILLUMINATION SHIP Russian patent published in 2023 - IPC G01S15/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to anti-submarine ships, the purpose of which is the search and detection of underwater objects and tracking them, that is, the illumination of the underwater environment. The ship for illumination of the underwater environment is equipped with a hydroacoustic emitter with a hydroacoustic antenna lowered under water to a predetermined depth and a set of passive autonomous hydroacoustic stations (AHAS) capable of detecting probing signals of a hydroacoustic emitter reflected from underwater objects, devices for measuring the characteristics of hydroacoustic conditions in the navigation area and communication equipment for receiving messages from the AHAS, a computer with a special program that allows, before starting work, to calculate the required number, coordinates of the installed AHAS, the manoeuvring trajectory of the ship, optimal for the current hydroacoustic conditions, the installation depth of the emitter antenna and AHAS, and to calculate the trajectories of detected underwater objects and determine their coordinates and movement parameters, the lowered hydroacoustic antenna is made in the form of a hydroacoustic extended towed receiving-transmitting antenna, AHAS is additionally capable of detecting noise signals from underwater objects and includes a GLONASS/GPS navigation receiver, equipment for transmitting messages about the detection of an underwater object and the coordinates of its location, and the AHAS design is combined with an adapted multicopter.

EFFECT: simplification of the manoeuvring trajectory when setting up the AHAS, operation of the underwater environment illumination system during any manoeuvres, increase in the controlled area of underwater observation and the possibility of using extended towed antennas.
