Abstract
A method of performing direction of arrival (DOA) estimation employs a weighted fitting estimator in which components from respective samples are weighted by respective derived weight values. The weight factors may simply be the amplitudes themselves. Compared with the conventional fitting for DOA estimation, embodiments of the present invention provide more efficient use of sample data and higher estimation accuracy, without significantly complicating the estimation algorithm compared to prior art techniques.
