METHOD OF GENERATING INTERFERENCE TO RADAR STATIONS WITH SYNTHETIC APERTURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2025 - IPC G01S7/38 H04K3/00 G01S13/90 

FIELD: camouflage; radio engineering.

SUBSTANCE: invention relates to the fields of camouflage and radio engineering, in particular to methods and techniques for electronic jamming of radar stations operating in aperture synthesis mode, and can be used when performing measures for masking objects from radar surveillance systems created on the basis of radar stations operating in aperture synthesis mode. Method of generating interference to radar stations with a synthetic aperture consists in modulating a signal received from a radar station operating in a synthetic aperture mode by an ensemble of generated signals at frequencies that are multiples of frequencies corresponding to the azimuth resolution of the radar station, modulated signal delays in delay lines by duration multiples of radar station resolution by range, and summation of delayed signals before emission in direction of radar station. Apparatus for generating interference to radar stations with a synthetic aperture for implementing the method further comprises a frequency synthesizer, a first and a second signal adder, a frequency modulator, a filter control unit and a delay line unit.

EFFECT: possibility of formation of barrage interference, providing concealment of areas of terrain exceeding dimensions of concealed object or group of objects, and simplifying the implementation of the device which generates interference to radar stations operating in the antenna aperture synthesis mode.
