METHOD FOR PROTECTION FROM PULSED INTERFERENCE (VERSIONS) Russian patent published in 2015 - IPC G01S13/00 

FIELD: radio engineering, communication.

SUBSTANCE: in the method for protection from synchronous repeater jamming, based on using a longer probing period, upon detecting signals at distances exceeding the maximum radar detection range of a real target, said signals are considered repeater jamming signals, the features thereof are determined and used to detect said interference along with received signals at any range. Said result according to the first version is achieved also due to that the feature used is angular coordinates of the beginning and the end of the spatial packet of signals, angular coordinates of the centre of the spatial packet of signals and the strength of the interference signals. Said result according to the second version is achieved also due to that in the method for protection from pulsed interference, based on using a longer probing period, upon detecting signals at distances exceeding the radar detection range of a real target, said signals are considered interference, the phase difference thereof is measured at spaced-apart reception points and then used as the feature of the interference. The technical result of the second version is achieved due to that the phase difference is determined between signals received by main and auxiliary radar antennae.

EFFECT: generating features of pulsed, and particularly, synchronous repeater jamming and recognition thereof at any range.
