Applications of cumulants to array processing - Part VI: Polarization and direction of arrival estimation with minimally constrained arrays

A fourth-order statistics-based method is presented for joint estimation of polarization and direction of arrival parameters of as many as M-l narrowb and signals with an M-element array having M-3 elements that are of arbitra ry and unknown response and geometry and a subarray consisting of three sho rt dipole antennas configured in a certain fashion. The method is computati onally efficient and offers considerable savings in hardware over a recentl y published second-order statistics-based method.
