Abstract

A smart antenna system with innovative signal processing can enhance the resolution of a signal direction of arrival estimation. Super resolution algorithms take advantage of array antenna structures to better process the incoming signals and they also have the ability to identify multiple targets. This paper presents a comparative performance study and geometrical optimization between MUSIC (Multiple Signal Classification), MVDR (Minimum Variance Distortionless Response) and Min Norm direction of arrival algorithms used in linear antenna array. We studied the effect of antenna array parameters in terms of its size and element spacing. In simulations we study the influence of angle of arrival on algorithm behaviour.
