JAMMING METHOD AND DEVICE (VERSIONS) Russian patent published in 2015 - IPC H04K3/00 

FIELD: radio engineering, communication.

SUBSTANCE: method comprises opening a hop set used in the jammed radio network, and the generation of an interfering signal with matched structure and a given duration begins at said frequencies during pause in operation of network subscribers. A jamming device comprises first and second antenna systems, a multichannel radio receiving device, an analogue-to-digital conversion unit, a signal selector, an operating frequency determining unit, a cutoff frequency determining unit, a hop set determining unit, an interference transmitter, a reference frequency unit with corresponding links, a pause determining unit, as well as a control unit in a second version of the device and a switch, a multichannel pause detection unit, a control unit, an adder, m-1 interference transmitters and m-1 second antenna systems in a third version of the device.

EFFECT: providing effective radio suppression of a given radio network with pseudorandom operating frequency adjustment with significant reduction of power consumption at the same time.
