  This paper presents the performance analysis of directions of arrival
estimation techniques, Subspace and the Non-Subspace methods. In this paper,
exploring the 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 elements and their spacing are also
investigated.
