Abstract

A least squares estimation technique for finding the directions of arrival (DOAs) of signals corrupted by additive white noise using a uniform linear array is developed. Although the estimates are not as accurate as those of subspace methods, the computations involved are simpler, and prior knowledge of the number of sources is not required.
