A new Direction of Arrival (DoA) estimation method based on Neural Networks (NNs) is presented. The proposed NN-DoA procedure is especially designed for a Switched-Beam System (SBS), whose basic component is an 8 £ 8 Butler Matrix (BM). The technique is simple and appropriate for real time applications. Simulations of DoA estimation tests show accurate results even for a big set of simultaneously incident signals.
