A CCM-based Pair-matching Method for Two-dimensional Arrival Angles Estimation

This paper focuses on the pair-matching problem of Two-Dimensional Angle-Of-Arrival (2-D AOA) estimation for the L-shaped array. The authors adopt a modified array configuration in which the azimuth and elevation angles can be exploited independently. Moreover, by such configuration, the Cross Correlation Matrix (CCM) is employed to accomplish pairing-matching between estimated parameters which obtained by a subspace approach. Numerical simulations verify the effectiveness and performance of the proposed method.
