FIELD: radio engineering and communication.
SUBSTANCE: invention relates to means of fighting mines and other explosive objects having radio fuses and is intended for protection against radio-controlled explosive devices by blocking unauthorized transmission of information on controlling radio fuses over a radio channel. Device comprises series-connected non-linear variable voltage generator, voltage-controlled generator, first and second amplifiers, first and second valves, first and second antennae, first and second controlled switches, a device for controlling said switches, third and fourth amplifiers, third and fourth antennae and a signal frequency multiplier. Voltage-controlled generator generates a harmonic signal, the frequency of which continuously varies over a period of time according to the law determined by the shape of the output signal of the nonlinear variable voltage generator.
EFFECT: higher probability of guaranteed jamming with fragmentary increase in energy density of interference signal in protected range.
