Abstract

In this paper, an improved estimation of signal parameters via rotational invariance techniques (ESPRIT) algorithm is proposed. As to the frequency scanning leaky wave antenna (LWA), the direction of arrival (DOA) can be effectively estimated by the algorithm. Compared with ESPRIT algorithm based on array antennas or electronically controlled beam scanning LWA, the ESPRIT algorithm using frequency scanning LWA obviously simplifies the hardware implementation. Furthermore, the wideband DOA can be simultaneously estimated by this proposed algorithm. The simulation results show that the estimated DOA results are in good agreement with the predicted angles, with root mean square error (RMSE) less than 1.6% on 38% relative bandwidth (ultra wide band).
