A Comparative Study of Statistical and Neural DOA Estimation Techniques

Abstract

In this letter, we compare the direction-ofarrival (DOA) technique based on the use of a radial basis function (RBF) network with the standard MUSIC algorithm. The RBF network is used to approximate the functional relationship between sensor outputs and the directionof-arrivals. Simulation results show that the new technique has a better performance, in terms of estimation errors.
