Abstract: A goniometry method for one or several diffuse (or distributed) sources is disclosed. The sources or sources having one or more give directions and a diffusion cone. The sources are received by an array of several sensors. The method breaks down the diffusion cone into a finite number L of diffusers. A diffuser has the parameters (?mp, ??mpi, ?mp, ??mpi), associated with it. Directing vectors a(?mp+??mpi, ?mp+??mpi) associated with the L diffusers are combined to obtain a vector (D(?, ?, ??, ??) ? or U(?, ?) ?(??, ??, ?)) dependent on at least one of the incidence and deflection parameters (?, ?, ??, ??) and on the combination vector ?. A MUSIC-type criterion or other goniometry algorithm is applied to the vectors D(?, ?, ??, ??) ? or U(?, ?) ?(??, ??, ?) obtained in order to determine at least one of the incidence parameters ?mp, ?mp, ??mp, ??mp of the associated diffusion cone.
