DEVICE FOR LOCKING RADIO PROXIMITY FUSES Russian patent published in 1999 - IPC

FIELD: protection against radio-controlled mines. SUBSTANCE: device has n frequency oscillators, wide-band power amplifier, wide-band antenna system, commutator, which n signal inputs are connected to outputs of frequency oscillators, and which output is connected to input of wide-band power amplifier. In addition device has pseudorandom pulse sequence generator, which is connected to control input of commutator 4, and controlled interface, which is inserted between wide-band power amplifier and wide-band antenna system, and parameters regulator which is connected to control inputs of wide-band power amplifier, controlled interface and n frequency oscillators. In addition each of n frequency oscillators operates in overlapping adjacent frequency bands and is designed as serial circuit of generator of non-linear alternating voltage, and voltage-controlled generator. EFFECT: increased reliability of protection against unauthorized transmission of information through radio channel in wide band of unknown frequencies without increase in integral output device power, its power consumption, size and weight, possibility of its on-line adjustment to current frequency conditions without alteration of its circuits and design. 2 cl, 2 dwg
