Abstract

Based on L-shaped array, three two-dimensional direction-of-arrival (2-D DOA) estimation algorithms are investigated. Root-MUSIC algorithm for 2-D DOA estimation obtains parameter via getting the roots of a polynomial. ESPRIT algorithm for 2-D DOA estimation uses the rotational invariance principle of matrix without spectral peak searching. Matrix Enhancement and Matrix Pencil(MEMP) algorithm forms a new augmented matrix by using covariance matrix of the receiving source signals. The three algorithms for L-shaped array are studied and simulated with MATLAB. The performance shows that high resolution, estimation precision and stability can be obtained with different SNRs.
