A method for radio - localization by determination of phases of electromagnetic waves and out of the method according to the receiver device for.

摘要

The present invention relates to the radio - location, with the aid of curves of iso - phase shift of the two waves of radio - frequencies rejected by a low frequency. These two waves are issued by a group of stations foci emitting in addition, a wave of reference associated with the two waves of the radio frequency forming a pair and modulated by said low frequency and of frequencies of levee of ambiguity. / p & & p & according to the invention, uses a single reception channel, carried out, during successive time periods f1, f2, f3, the determination of the low frequencies on the basis of the fundamental wave and the determination of the low frequencies of reference, corrected by calculation, the values thus obtained to dispose of the spacing difference in time and then compares the values corresponding after the correction to the same instants of time, in order to obtain the phase shifts. / p & & p & the invention is usable for the radio - location of a ship.
