SYSTEM FOR INSPECTING SHIPBORNE RADAR SYSTEM Russian patent published in 2009 - IPC G01S7/40 

FIELD: physics.

SUBSTANCE: invention relates to devices for inspecting radar systems. The essence of the proposed engineering solution lies in that, in the system for inspecting a radar system, which includes a monitoring antenna, first simulator of reflected signals and standard equipment for a shipborne radar system, the standard equipment has an integrated antenna assembly, which includes a unit of slowly rotating antennae with a rotary actuator and unit of stabilisation actuators, radar station (RS) as part of a device for high-frequency (HF) switching of the radar station, transceiver, which generates pulsed probing signals and when processing received reflected signals, generates pulsed video signals, which, through the device for displaying and controlling the radar station, are transmitted to the second data input of the device for processing signals and converting information of the radar station, as well as a transmitting device, which generates quasicontinuous linear frequency modulated (LFM) probing signals, and a device for receiving the linear frequency modulated signals, the output of which is connected to the first data input of the device for processing signals and converting information of the radar station, and a passive radar station (PRS), which includes an antenna assembly for detecting the passive radar station, which includes a unit of fast rotating antennae and a unit for band-pass filtering and amplification, a device for amplifying and high-frequency switching the passive radar station, first, second and third receiving devices for the passive radar station, device for converting, displaying and controlling the passive radar station and a device for analysing the passive radar station and outputting data, and the test and control equipment also includes a second simulator of reflected signals, connected to the control input-output of the transceiver, radar station noise generator, connected to the control input of the device for receiving linear frequency modulated signals, passive radar station noise generator, connected to the monitoring antenna, built-in control devices in the transceiver, transmitting device, device for receiving linear frequency modulated signals and receiving devices of the passive radar station, device for monitoring changes in frequency deviation and a device for monitoring changes in the output power, connected to the output for signals at the first heterodyne frequency and to the signal output of the transmitting device, respectively, a device for monitoring sensitivity of the transceiver, connected to the signal input-output of the said device, device for monitoring the passive radar station, which includes a measuring antenna and a group of high-frequency generators operating in the frequency range of the passive radar station, as well as an external communication console and a lag signal simulator and a gyro course indicator.

EFFECT: technical outcome is high reliability of results of complex testing a radar system in all its operating modes.
