Abstract
A method for jointly determining the azimuth angle θ and the elevation angle Δ of the wave vectors of P waves in a system comprising an array of sensors, a number of waves out of the P waves being propagated along coherent or substantially coherent paths between a source and said sensors, includes at least the following steps: selecting a subset of sensors from said sensors to form a linear subarray of sensors; applying, to the signals from the chosen subarray, an algorithm according to a single dimension to decorrelate the sources of the P waves; determining a first component w of said wave vectors by applying, to the signals observed on the sensors of the chosen subarray, a goniometry algorithm according to the single dimension w; determining a second component u of said wave vectors by applying a goniometry algorithm according to the single dimension u to the signals from the entire array of sensors; determining θ and Δ from w and u.
