Conjugate Augmented Spatial Temporal Technique for 2-D DOA Estimation With L-Shaped Array

ABSTRACT:

To solve the angle ambiguity downside when multiple sources have the same azimuth or elevation angles, a completely unique two-dimensional direction of arrival (2-D DOA) estimation method with L-shaped array based mostly on conjugate augmented spatial temporal technique is developed in this letter. The essential plan of the proposed technique is to utilize the conjugate symmetry property of the signal auto-correlation function with different delays to construct a conjugate augmented spatial-temporal cross-correlation matrix (SOLID-CCM) and form joint diagonalization structure from the signal subspace reminiscent of the SOLID-CCM. Hence, the DOAs are estimated and paired automatically via joint diagonalization technique. The proposed method will handle the angle ambiguity problem efficiently and can conjointly work in the underdetermined case. The effectiveness of the proposed technique is verified through laptop simulations.
