Abstract Based on a parallel uniform linear array and fourth order cumulant, a new approach for estimating multiple spatial narrow-band signal 2-D directions of arrival separately in the arbitrary Gaussian noise environment is presented. With flexible definition of fourth order cumulant of the array output signal, the spectral peak searching is not necessary for the new separable approach. Computer simulation confirms its availability.
