This paper deals with spatio-temporal analysis. The measurement of the directions of arrival using an antennas array is limited by the number of detected sources. In a linear network of M antennas, the maximum number of not correlated signals that can be localized is (M-1), and (2M/3) in case of correlated signals. Thus, the number of antennas must be higher than the number of signals. The spatio-temporal...
This paper proposes two Unitary MUSIC-like algorithms, requiring only linear operations, for Directions of Arrival (DoAs) estimation problem. The constraints on the proposed algorithms are the same imposed onto the standard MUSIC algorithm allowing high resolution localisation capabilities with a reduced computation cost and lower processing time as compared to the existing schemes. We demonstrate...
In this paper, a new design of Electronically Steerable Parasitic Array Radiator (ESPAR) antennas is proposed for directions of arrival (DoAs) estimation of coherent sources by the well known ESPRIT algorithm. The Spatial Smoothing technique (SS) is adapted to this antennas shape to remove signals' coherence. The excellent performances of the uniform circular geometry are used to ensure accurate DoAs...
