We propose a new simple and accurate approach to localize two equipowered plane-wave sources (i.e., harmonics) using a uniform linear array (ULA) of sensors. We exploit the particular form of the covariance matrix jointly with a least square fitting (LSF) to derive new simple closed-form expressions for the directions of arrival (or harmonics in general). Simulation results demonstrate that resorting to this new method, mainly in the case of very low angular separation, and even with a limited number of sensors, leads to highly accurate results while requiring low computational complexity.
