Abstract

This paper investigates the performance of different parameter estimation algorithms in direction finding using a linear array with element spacing of more than half a wavelength. The study shows that all the common algorithms namely the beamformer methods, MUSIC, Min-Norm, JoDeG, ESPRIT, and SAGE, generate an ambiguous error in the estimated direction-of-arrival results, when the antenna element spacing is more than half the carrier wavelength. Here, the source of this ambiguity is identified, and our proposition confirmed by applying the algorithms on the real measured data in a controlled environment. Furthermore, the relative sensitivity of each candidate algorithm is appraised
