摘要：

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 methods that are based on a joint estimation (angle-delay), overcome this difficulty. Here, a comparative study between two high-resolution wide-band algorithms that simultaneously estimate the travel time and the angle of arrival of the paths is presented. We will highlight the advantages of these two methods in the case of a joint estimation (angle-delay), via simulations.
