FIELD: radio communications.
SUBSTANCE: device uses modulations of central frequencies, transmitted linear frequency-modulated radio pulses according to information law, for which purpose receiving side additionally has dispersion compression filter, key, multiplexer and block for forming selective control pulses and for picking information signals. Also, synchronized filtering is provided with weight processing of information signals and temporal selection of time-compressed video pulses for restoration of information signal.
EFFECT: decreased occupied space of frequency spectrum 2,5 times, higher resistance to interference.
