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

FIELD: radio engineering, communication.

SUBSTANCE: repeater jamming method involves coherent reception of radio signals at a given frequency using antennae which form an antenna array, and a multichannel receiver, detecting a signal, generating and radiating interference from the far wave zone of the antenna array upon detecting a signal, wherein received radio signals at the moment of radiating interference are phased with compensation of phase incursion from the point of radiation to antennae; the phased radio signals are averaged on the set of antennae; the averaged radio signal is phased to restore the compensated phase incursions of the antennae; and formed difference radio signals are subtracted from the corresponding received radio signal at the moment of radiating interference, and at moments without interference radiation, the received radio signals are detected and averaged on the set of antennae, and signal detection is carried out by comparison with the detection threshold of averaged detection results.

EFFECT: high efficiency of jamming radio lines with short-term radiations, multiple radio lines with different transmission durations while reducing the cost of interfering resource.
