RADIO-CONTROLLED APPARATUS BLOCKER Russian patent published in 2021 - IPC H04K3/00 F41H11/12 

FIELD: radio equipment.

SUBSTANCE: invention relates to means of combating explosive objects equipped with radio fuzes by blocking unsanctioned transmission of control information by radio fuzes over a radio channel, and can also be used for protection against unsanctioned transmission of any information over a radio channel in a wide range of previously unknown radio frequencies. The apparatus comprises a first 1, a second 2, a third 3 and a fourth 4 non-linearly changing periodic voltage generators, wherein each generator provides a specific amplitude range, a first 5, a second 6, a third 7 two-input controlled switches, a voltage-controlled oscillator 8 (VCO), a bandpass filter 9, a power amplifier 10 and a transmitting emitting antenna 11, a control apparatus 12, an inverter 13, a binary counter 14, a bandpass filter and apparatus 15 for synchronisation of linearly changing voltage generators, the output of the apparatus 15 for synchronisation of linearly changing voltage generators is connected to the synchronisation inputs of the linearly changing voltage generators 1, 2, 3 and 4.

EFFECT: technical result is the increased probability of guaranteed radio suppression.
