MONOPULSE RADAR WITH THROUGH PHASE CHANNELS Russian patent published in 2004 - IPC

FIELD: radio detection and ranging, applicable in air traffic control systems.

SUBSTANCE: the monopulse radar with through phase channels includes controlled phase shifters equalizing the phases of the monopulse channels by a signal produced with the aid of a remote reference transponder by a signal produced by the automatic phase-lock control unit, delay register, error analyzer, and the automatic phase-lock control unit is made in the form of a computer unit and a control unit, with the delay register connected between them, the output of the computer unit is connected via the error analyzer to the control input of the delay register. The error of measurement of the azimuth of CD is subjected to analysis for certainty with the aid of the error analyzer: operation of the automatic phase-lock control unit in case of a jamming, and consequently, correction of phase relationships in the channels is delayed by the time of action of jamming.

EFFECT: enhanced antijamming of the device.
