Abstract
A technique for locating sources interfering on a signal received by a receiver comprising an array of antennas calculates a spatio-temporal intercorrelation matrix Rxx, and determining the eigenvectors {U1, U2, . . . UN} of the spatial intercorrelation matrix R(b), and determining the directions of arrival of the interfering sources by searching for the vectors of relative gains belonging to the said interference sub-space or which are orthogonal to the orthogonal noise sub-space and complementary to the interference sub-space.
