摘要：

This letter presents a novel method for pair matching of elevation and azimuth angles in two-dimensional (2-D) angles-of-arrival estimation employing two uniform linear arrays (ULAs). The proposed pair-matching method exploits the cross-correlation matrix of two received signals impinging on each ULA that shows the characteristics of the corresponding angle pairs, and is conducted by combining it with a propagator method. Numerical simulations using L-shaped array geometry revealed that the Proposed method provided better robustness over the SNR, angular separation, and number of sources than that of conventional methods.
