SHIPBOARD THREE-DIMENSIONAL RADAR STATION AND ANTENNA ARRANGEMENT FOR IT Russian patent published in 2005 - IPC

FIELD: the invention refers to the field of radiolocation particularly to shipboard radar stations and may be used for detection of air and surface targets and target designation.

SUBSTANCE: the shipboard radar station has an antenna of the first channel, a multi channel rotating joint, an antenna switch of the first channel, an arrangement of protection of the receiver of the first channel, a super-high-frequency receiving arrangement of the first channel, a transmitting arrangement of the first channel, an arrangement of automatic adjusting of amplification of the first channel, a selector of moving targets, an arrangement of limitation and matched filtering, an arrangement of strobing of one-digit signals, an arrangement of blanking signals, an attenuator of the first channel, an arrangement of detecting and multiplication of signals, the first output of which is the output of the radar station, an arrangement of reflection of information and of control of regimes, an arrangement of processing of information, an arrangement of forming linear frequency modulated signals. At that an antenna of the second channel is introduced in it, an arrangement of drives and stabilization, an arrangement of drives control, the first arrangement of summation and division of frequency channels, a waveguide rotating joint, an arrangement of switching regimes "equivalent" - "antenna", the second arrangement of summation and division of frequency channels, an antenna switch of the second channel, an arrangement of protection of the receiver of the second channel, a super-high-frequency receiving arrangement of the second channel, a transmitting arrangement of the second channel, an arrangement of automatic adjusting of amplification of the second channel, an attenuator of the second channel. The antenna arrangement has a receiving-transmitting antenna installed on body with possibility of circle rotation in horizontal plate. At that the second receiving-transmitting antenna is introduced. It is working in the other sub-band of frequencies and installed jointly with the first on the body so that antenna radiated signals are directed in mutually antithetic direction. AT that driving arrangements are implemented for mechanical stabilization along rolling and pitching.

EFFECT: increases temps of renovation of information, high accuracy of measuring of the target coordinates and target designation with enhanced distance of detection including small size low flying targets.
