SYSTEM FOR BUILT-IN CONTROL AND CALIBRATION OF MONOPULSE RADAR STATION Russian patent published in 2012 - IPC G01S7/40 

FIELD: physics.

SUBSTANCE: during control, a portion of probing signal power, which is fed to a circuit signal simulator and through a circulator to an adder with a heterodyne simulator signal, is output from a monopulse radar station; the resultant signal is fed to a mixer, conveyed at an intermediate frequency and is fed to a recirculation circuit, which is built on series-connected second adder and delay line, where the damped batch of delayed pulses returns to the mixer, where it is conveyed at carrier frequency using the heterodyne signal, passes through the circulator to series-connected valve, test antenna and radio communication channel to the antenna of the monopulse radar station. The processor of the monopulse radar station controls the process of built-in control in signal search, capture and tracking modes; measurement of bearing characteristics takes place based on target search results with scanning of the antenna system; capturing and tracking results are used to determine coordinates of the simulated target, controlled parameters of the transmitter, the receiver and signal of the detector; by comparing the controlled parameters with rated values, the processor determines accuracy of the monopulse radar station and deviation of calibration, which it then stores and takes into account when measuring coordinates of targets during combat.

EFFECT: controlling units of a monopulse radar station during operation, verifying calibration, which enables to take into consideration deviation thereof before combat.
