Abstract
In this letter, it has been shown how an electronically steerable parasitic array radiator (ESPAR) antenna can be used for 2-D direction-of-arrival (DoA) estimation employing received signal strength (RSS) values only. The proposed approach relies on changes in RSS values recorded at the antenna output port observed for different vertical and horizontal directions, while antenna’s main beam sweeps 360° area around the ESPAR antenna. Based on the observed diversity in RSS values, obtained for different ESPAR antenna radiation patterns and different directions of a signal impinging the antenna, a simple 2-D DoA estimator has been proposed. Measurements using the fabricated ESPAR antenna indicate that, by relying solely on RSS values and the proposed algorithm, it is possible to perform 2-D DoA estimation with the acceptable accuracy in realistic and inexpensive systems, where the phase of impinging signals cannot easily be measured.
