Literature Survey on High Resolution Direction of Arrival (DOA) Algorithms

Abstract: This paper is an extensive study on realization of high resolution array based direction of arrival (DOA) estimation techniques which deals with beam forming. The techniques detailed include the conventional beam forming type of algorithms, maximum likelihood algorithms, the high resolution subspace based algorithms. The performance of MUSIC, ESPRIT, Minimum norm, and conventional beam forming techniques have been estimated using MATLAB. Based on the results realization of high resolution direction of arrival is achieved. Keywords: direction of arrival; beam forming; high resolution; maximum likelihood; subspace.
