ANTENNA POST OF INDEPENDENT RADAR CONTROL SYSTEM Russian patent published in 2017 - IPC H01Q1/00 

FIELD: radio engineering, communication.

SUBSTANCE: segregation of antennas by frequency range frequency allows to optimize frequencies for acquisition and tracking of targets. Using a controlled polarization in tracking antenna allows to improve noise immunity of the control system from barrage active jamming, including from active jamming matching by angles and range with a target, as well as from passive jamming. Simultaneous and independent operation of antennas decreases the response time, i.e., during tracking of conditionally first target by the tracking antenna the observation antenna prepares input data for the tracking antenna for other targets, providing their capture for auto tracking without additional search.

EFFECT: improvement of noise immunity of a control system from barrage jamming, including the jamming matching by angles and range with a target, as well as from passive jamming, optimization of frequency for target acquisition and tracking, and providing simultaneous and independent operation of antennas with different frequency ranges.
