A method for determining the angles of arrival or the direction of arrival of multiple paths associated with a transmitter or a source Ei in a system comprising N reception antennae, one of said antennae (4 1) being a reference antenna continuously linked to a first receiver (3 1) and the N-1 other antennae being discontinuously linked to a second receiver (3 2) by means of a two-way switch, said reference antenna (4 1) continuously receiving a signal x 1 (t), said signal comprising a reference sequence d(t), characterised in that it comprises at least the following steps: • carrying out a symbol synchronisation on said reference antenna (4 1), then estimating the passage matrix between the signal x 1 ( nT s) received on said reference antenna and the reference symbols d n, where T s is the symbol time; • generating two filters that will allow the symbols c n on both sides of said reference sequence d(t) made up of said symbols d n to be estimated and detected; • estimating the channel matrix A l i.Ω.
