METHOD FOR RADIO SUPPRESSION OF COGNITIVE RADIO COMMUNICATION SYSTEMS Russian patent published in 2020 - IPC G01S7/495 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, namely to artificial interference generation, and can be used for radio suppression (RS) of cognitive radio communication systems (RCS), information on used working frequencies of which is unknown and cannot be determined. RCS RS method consists in analysing frequency band ΔF, receive signals from radiation sources in frequency band ΔF within a cycle time Tp, the frequency band ΔF is divided into N subbands with frequency intervals Δƒ_n in accordance with operating frequency subbands of allowed radio electronic devices operating in frequency band ΔF, in all subbands of frequency band ΔF, with the exception of subbands in which currently permitted radioelectronic equipment is operating, and subbands which are programmed in accordance with the electromagnetic environment, which are optimal for jamming, emitting pulse interference signals of a certain duration and power such that a RCS decision is made on inadmissibility of operation at said frequencies, and for radio exchange of RCS there selected are pre-programmed subbands, in which interference signal is absent, upon detection of RCS operation in subbands free from interference radiation, transmitting transmission mode and structure modulating voltage control signals are generated, modulating, amplifying and emitting impact interference signals, wherein new subbands proposed for RCS operation are programmed.

EFFECT: technical result of this invention is broader functional capabilities of the system of electronic suppression by hindering or disrupting training of cognitive radio communication systems.
