RETRANSMITTED JAMMING METHOD Russian patent published in 2014 - IPC H04K3/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering and can be used for radio-electronic protection of an object dislocation area from radar surveillance. The retransmitted jamming method includes receiving probing signals of the side-looking radar of each jamming station arranged around the periphery of the protected area; measuring the duration and repetition period of probing signals; generating repeatedly radiated interference, correlated with probing, in form of patterns of the received signals; introducing radiation delay of the patterns of the received signals and interference carrier frequency shift, measured according to a program from period to period of the repetition of probing signals; receiving signals of the radio navigation space-based system GLONASS; radiating said interference with oblique polarisation; picking up code signals from the structure of space radio signals; generating, when picking up code signals, reference pulse sequences and use thereof in jamming and synchronising jamming stations operating collectively.

EFFECT: reducing radar contrast of an object relative to false targets and underlying surfaces owing to radio-electronic imitation of the latter, facilitating the speckle effect which disrupts the radar image of the object.
