FIELD: radio countermeasures.
SUBSTANCE: invention relates to means of combating explosive objects having radio fuses by blocking unauthorized transmission of radio fuse control information over a radio channel, and can also be used to protect against unauthorized transmission of information over a radio channel. The device contains the first, second, third and fourth generators of non-linearly varying periodic voltage, each of which provides its own amplitude range, the outputs of which are connected to the inputs of the first, second, third and fourth voltage-controlled generators, respectively. The first two-input controlled switch is connected to the first individual control device. The second two-input controlled switch is controlled by a second individual control device. The outputs of the first bandpass filter and the second bandpass filter are connected to the inputs of the signal adder. The output of the third bandpass filter is connected to the input of the power amplifier, the output of which is loaded onto the transmitting radiating antenna.
EFFECT: probability of guaranteed radio suppression increases.
