INCIDENT SIGNAL PARAMETERS ESTIMATION ON ANTENNA UNIFORM LINEAR ARRAY

Abstract

This paper presents a tool for the modeling, analysis, and simulation for extraction of the Directions of Arrival (DOA) of several signals impinging on uniform linear arrays. The first part of this paper describes the Multiple Signal Classification (MUSIC) technique of direction of arrival estimation and simulation method. The second part presents some illustrative simulation cases of MUSIC-DOA estimation by using Graphical User Interface) GUI(. Simulation results are analyzed by using Matlab program in order to conclude on the algorithm's accuracy and reliability. To demonstrate the versatility and accuracy of the developed tool, it is used to study the effect of changing a number of parameters related to the signal environment as well as the antenna array.
