INTEGRATED ANTENNA DEVICE OF RADIOELECTRONIC EQUIPMENT OF AUTONOMOUS UNMANNED UNDERWATER VEHICLE Russian patent published in 2020 - IPC H01Q1/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to complex antenna devices (CAD) of radioelectronic means (REM) for installation on underwater vessels, mainly on heavy autonomous, long-range unmanned underwater vehicles (AUUV) for reception and transmission of radio signals in kilometer, meter, decimetre and centimeter range of electromagnetic waves. AUUV complex antenna device module comprises functionally connected to instrument part of corresponding radioelectronic means satellite navigation system (SNS) antenna, satellite communication system (SCS) antenna and VHF-modem antenna, as well as a radio electronic signal detection antenna (DRS) installed at the end of the mast of a sliding mast device with the possibility of lifting the antenna mast upwards perpendicular to the longitudinal AUUV axis. Instrument part of the corresponding radioelectronic facilities of the CAD module and the lifting-mast device are arranged in a vertical feed stabilizer AUUV. CAD module additionally includes a towed cable radio antenna (TCRA), made with positive buoyancy, a GSM-modem antenna, an underwater radio communication modem antenna for communication with a underwater stationary installation (USI). Upper part of the vertical stern stabilizer is made in the form of a teardrop fairing, and the lower part of the stabilizer is made in the form of a tray in the form identical to the shape of the seat, which is made in the AUUV casing for installation and attachment of a CAD module on it with possibility of removal of the whole module from the seat. Instrument part of the radioelectronic facilities of the CAD module further comprises functionally interconnected amplification and matching units of antenna signals, a switch, DAC, ADC and a CAD control device. Instrument part is placed in a sealed housing, which is installed on a tray in the CAD module, and the control device of the CAD module instrument part is functionally connected to the AUUV onboard control and navigation system (BCNS). Lifting-mast device, on the antenna mast of which the antenna for detecting radio-electronic signals (DRS) is installed, is placed on a tray in a CAD module and is equipped with a sealed electric drive, wherein the antenna mast is installed in a CAD module with the possibility of lifting the DRS antenna above the cowling body. Antenna platform is made at the nose of the CAD module, on which VHF modems, GSM-modems, SCS and SNS antennas are installed. In the aft end of the fairing, an antenna of the underwater radio modem is installed for communication with the USI. In the aft end of the fairing body along its longitudinal axis there is also a TCRA release device in the sea. TCRA is arranged on winch drum equipped with electric drive in sealed version, the winch itself is rigidly installed on tray in CAD module, and between the winch drum and TCRA release device in the sea there is a cable channel with the possibility of TCRA movement on it when it is released into the sea or winded on the drum of the winch.

EFFECT: broader functional capabilities of the CAD AUUV module owing to the AUUV control and information transmission when the AUUV is in both the surface and underwater positions and, in addition, the technological enhancement of the CAD module in the AUUV.
