FIELD: radio equipment engineering.
SUBSTANCE: system has base station, consisting of narrowband signal transmitter and receiver of complicated phase-manipulated signal, and client station, consisting of transmitter of complicated phase-manipulated signal and receiver of narrowband signal, in which support frequencies mesh generator and commutator are inserted. Transmitter of complicated phase manipulated signal of reverse channel additionally includes block for protection from narrowband interference. Transmitter of narrowband signal has serially connected narrowband signal generator, amplitude modulator and power amplifier.
EFFECT: higher resistance to narrowband interference while satisfying requirements to portability of client station and energetic concealment of its signal.
