radio communication, applicable in space and ground-based radio communication systems with a repeated use of frequency. SUBSTANCE: on the transmitting side the device has a generator of signals of the main messages, power splitter, first and second amplitude modulators, paraphase amplifier and a transmitting antenna, on the receiving side - a receiving antenna, adder, subtracter, synchronous detector, amplitude limiter, demodulator, narrow-band low-pass filter, and a polarization reversal device. Introduction on the transmitting side of a frequency synthesizer, decoder, standard frequency assembly, and a PR sequence generator, and on the receiving side - of a standard frequency assembly, clock driver, synchronizer, divider, shift register, code translator, frequency synthesizer, n-keys and n-band-pass filters, adder and mixer, first and second band-pass filters, processing unit a low-pass filter made it possible to considerably accelerate the search for the receiving signal and improve the noise immunity to concentrated and impulse noise. EFFECT: enhanced efficiency. 3 dwg
