Abstract

An array antenna system with innovative advanced signal processing can reduce the direction of arrival (DOA) estimation variance. This paper presents the DOA estimation by estimation of signal parameters via rotational invariant technique (ESPRIT). Two different array antennas are used in this simulation study. The DOA performance as a function of signal to noise ratio (SNR), number of snapshots and effect of spatial smoothing are discussed in this paper. The position of array antenna elements may deviate from the ideal location. The imprecise element position will increase the DOA estimation variance. Sensitivity analysis due to non-ideal element position is also discussed in this paper.
