Abstract

In this paper, direction of arrival estimation has been addressed using derivative free methods and their hybrid procedure in antenna array signal processing. The problem has been formulated in the root mean square error sense by considering the single snapshot. A scenario based simulation has been performed by taking different number of antenna elements with varying sources. The stability, reliability and applicability of the proposed scheme has been monitored by Monte Carlo simulation and their statistical analysis based on the fitness of the problem, global mean square error and computational budget in term of time complexity.
