Applications of cumulants to array processing. Part VI. Polarization and direction of arrival estimation with minimally constrained arrays
E. Gonen, Jerry M. Mendel · IEEE Transactions on Signal Processing · 1999
A fourth-order statistics-based method is presented for joint estimation of polarization and direction of arrival parameters of as many as M-1 narrowband signals with an M-element array having M-3 elements that are of arbitrary and unknown response and geometry and a subarray consisting of three short dipole antennas configured in a certain fashion. The method is computationally efficient and offers considerable savings in hardware over a recently published second-order statistics based method.
