Abstract: The present invention relates to a method and a receiver for radionavigation, said receiver comprising a single filter mounted downstream of a mixer and adapted to allow the passage of the composite signal formed by the superposition of the signals of lower frequency at the output of the mixer, a sampler intended to sample the composite signal filtered at a predtermined frequency (f.sub.e), a unit intended to produce by a frequency analysis operation a series of signals including the same frequency components as the composite signal and means adapted to establish the phases and, if appropriate, the amplitude of the signals produced in the receiver by correlating these signals with the samples obtained from the sampler.
