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