Abstract
In this paper, the effect of the geometry of planar antenna arrays on the accuracy of Direction of Arrival (DOA) estimation of impinging signals is studied. The expressions of Cramer-Rao Bounds (CRB) for the two-dimensional (2-D) DOA estimation are derived. Based on the hexagonal, square, L, cross and Y shaped antenna arrays, the CRBs of the elevation and azimuth angles of estimated DOA are investigated according to the received power ratio of signal to noise (SNR) and the fixed and the changing direction of impinging signal.
