This paper presents the performance analysis of directions of arrival estimation techniques, Subspace and the Non-Subspace methods. In this paper, exploring the Eigen-analysis category of high resolution and super resolution algorithms, presentation of description, comparison and the performance and resolution analyses of these algorithms are made. Sensitivity to various perturbations and the effect of parameters related to the design of the sensor array itself such as the number of array

... ts and their spacing are also investigated. The analysis is based on linear array antenna and the calculation of the pseudo spectra function of the estimation algorithms. Algorithms namely Delay-and-sum, Capon's, MUSIC, and ESPRIT Direction Of Arrival Estimates. MATLAB™ is used for simulating the algorithms.
