PROPOSAL OF A METHOD 2D-DOA FOR CORRELATED SOURCES USING L SHAPE ANTENNA ARRAY

Abstract

This article presents a method for identifying direction of arrival angle both the elevation angle and the azimuth (2D-DOA) of correlated sources based on L shape antenna array when the noise model has the symmetric Toeplitz covariance matrix. This method applies for the small SNR signals with a few snapshots by using a transformation matrix to transform into a new covariance matrix to eliminate noise components. In particular, the use of the PM algorithm allows to greatly reduce the computational complexity because there is no Eigen Value Decomposition. The results are tested, evaluated and compared with the MUSIC algorithm through simulation on the Matlab software.
