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 (θ, δθ, Δ, δΔ), associated with it. Directing vectors a(θ+δθ, Δ+δΔ) associated with the L diffusers are combined to obtain a vector (D(θ, Δ, δθ, δΔ) α or U(θ, Δ) β(δθ, δΔ, α)) dependent on at least one of the incidence and deflection parameters (θ, Δ, δθ, δΔ) and on the combination vector α. A MUSIC-type criterion or other goniometry algorithm is applied to the vectors D(θ, Δ, δθ, δΔ) α or U(θ, Δ) β(δθ, δΔ, α) obtained in order to determine at least one of the incidence parameters θ, Δ, δθ, δΔof the associated diffusion cone.
