Direction of Arrival Using 2-D Matrix Pencil Method

Abstract

In this research work, we proposed a technique to decrease the complexity of 2-D Matrix Pencil (MP) for the direction of arrival (DOA) evaluation by combining two perpendicular arrays: The first one is the uniform linear array (ULA) and the second one is a uniform circular array (UCA). This special structure for the 2D Matrix Pencil pipe to a powerful methodology for real-time implementation on a digital signal processor, while the MP used to correlated and uncorrelated sources with the presence of a white noise. The obtained results show that proposed MP method gives better results at the level of the precision and the estimation of the DOA compared to the published measure.

Two Dimensions Enhanced Matrix Pencil for Direction of Arrival

“…In this section, we analyze the Matrix Pencil investigated at this research and compared with the experimented one [13][14][15] for circular array of eight circular sector antennas, with d = 0.6 λ. This network receives the desired signal at an angle of 50 degrees, interference at angles of 25 and 80 degrees and the SNR = 20 dB.…”
