Abstract
This work presents a new proposal for the direction of arrival detection for more than one signal arriving simultaneously on an antennas array of linear or planar geometry using intelligent algorithms.The direction of arrival (DOA) estimator is developed using the techniques of digital conventional beamforming, blind source separation (BSS) and the neural estimator modular structure of radial basis functions (MRBF). The developed MRBF has its capabilities extended due to the interaction with BSS technique, which makes an estimation of the steering vectors of the multiple plane waves that reach the array at the same frequency, that is, it separates mixed signals without a priori information.
