Method for locating sources interfering with a satellite-based radionavigation signal comprising the following steps: a step of calculating the intercorrelation matrix Rxx of the signals received by the elementary antennas of the said array, a step of determining a plurality of pointing vectors Ss whose components are the antenna gains, in a given direction of pointing {right arrow over (u)}s, of each elementary antenna of the said array, a step of calculating, for each assumption of direction of pointing {right arrow over (u)}s, the power of the signal received in this direction by the array of antennas, a step of searching for maxima among the set of powers Psf calculated and of locating interfering sources in the directions of pointing {right arrow over (u)}s corresponding to the said maxima, an ambiguity resolution step consisting in eliminating, from the search step, the maxima relating to an ambiguity resulting from the geometry of the array. |
