NEW FAST ALGORITHM FOR 2-D ANGLE-OF-ARRIVAL ESTIMATION

<正>Based on propagator method, a fast 2-D Angle-Of-Arrival (AOA) algorithm is proposed in this paper. The proposed algorithm does not need the Eigen-Value Decomposition (EVD) or Singular Value Decomposition (SVD) of the Sample Covariance Matrix (SCM), thus the fast algorithm has lower computational complexity with insignificant performance degradation when comparing with conventional subspace approaches. Furthermore, the proposed algorithm has no performance degradation. Finally, computer simulations verify the effectiveness of the proposed algorithm.
