A new direction of arrival (DOA) estimation method with eigenvector based radial basis function neural network (RBFNN) was presented. This new method is not sensitive to noise and takes fewer training data to get RBFNN with good generalization ability. The computer simulation shows that the RBFNN trained with this algorithm is excellent at DOA estimation, and it is more suitable for real time application than classic superresolution algorithms. This DOA estimation method is promising in smart antenna of CDMA communication.
