FIELD: radio engineering.
SUBSTANCE: invention relates to means of combating mines and other explosive objects having radio fuses; it is intended to protect against radio-controlled explosive devices. The device contains the first generator of periodic non-linearly varying voltage, the first voltage-controlled generator, a constant voltage setpoint with the possibility of changing it, the second voltage-controlled generator, a two-input signal adder, a bandpass filter for the entire range of protected frequencies from the lower frequency fl to the upper frequency fu, a two-position switch, and a control device for this two-position switch, a voltage meter of the generator of non-linearly varying voltage, a setpoint of voltage proportional to the lower limit of a frequency window, a setpoint of voltage proportional to the upper limit of the frequency window, a device for switching on a frequency window mode, a transmitter, a bandpass filter for the entire range of protected frequencies from the lower frequency fl to the upper frequency fu, a power amplifier, and a radiating antenna.
EFFECT: information space is increased when the interference signal is active in the protected range.
