METHOD FOR RADIO SUPPRESSION OF COMMUNICATION CHANNELS Russian patent published in 2020 - IPC H04K3/00 G01S7/38 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, namely to engineering of creation of artificial radio interference, and can be used for radio suppression of radiation sources, a priori information on operating frequency of which is not known, including using mode with pseudo-random tuning of operating frequency. Disclosed is a method of radio suppression of communication channels, in which presence of external radio radiations within each of N subbands is checked. And the interference signal is sequentially emitted only on those M≤N subbands, starting from the first, on which operation of external radio radiations is not detected. Duration of emission of the interference signal t_i is selected such that for the minimum value of time t_min, the interference signal is emitted on each of the M subbands, on which no operation of external radio waves is detected.

EFFECT: technical result is increase of time interval of coincidence of noise signal and suppressed signal.
