FIELD: controlling.
SUBSTANCE: invention relates to means for fighting mines and other explosive objects equipped with radio fuzes, and is intended to protect against radio-controlled explosive apparatuses. The invention can also be used to protect against unsanctioned transmission of any information via a radio channel in a wide range of previously unknown radio frequencies. Fig. 1 depicts a block diagram of the claimed apparatus. The apparatus for blocking radio-controlled fuzes is comprised of a control apparatus 1, a microprocessor 2 selecting, controlled by a signal from the control apparatus, one of the programs selecting both the amount of frequency sub-ranges and the sequence for sending an interference harmonic signal to said sub-ranges and the rate of switching between sending over the protected frequency sub-ranges and sending within a separate range, a frequency synthesiser 3, a band-pass filter 4, a power amplifier 5 and an emitting antenna 6. The control apparatus 1 outputs a signal received by the input bus of the microprocessor 2 selecting, according to the input signal, the corresponding program with an algorithm for the frequency synthesiser 3. The output signal of the frequency synthesiser 3 passes through the band-pass filter 4 of the protected frequency range from the lower frequency fl to the upper frequency fu, wherein said filter filters high-order harmonics, is received by the input of the power amplifier 5, loaded on the emitting transmitting antenna 6.
EFFECT: increased probability of guaranteed radio suppression.
