FIELD: radio engineering, communication.
SUBSTANCE: method of phasing radio signals emitted from spaced-apart points of a moving object, with action of said signals on radar stations with target selection according to speed, can be used in a radar station. The method is realised by generating, at each of said points of the object, paired signals and successively emitting said signals; frequency shifting between signals in a pair is carried out equal to the first intermediate frequency of the receiver of the radar station; when relaying a radio signal received from the radar station, frequency shift of each pair is carried out by the same value with separate selection of upper side and lower side frequencies, thereby introducing a direct detection mode into the radar station and maintain coherence and phase opposition of the signals; the dephasing action of the reflected signal is prevented by frequency deviation and overlapping the received oscillation with narrow-band noise.
EFFECT: high efficiency of phasing.
