Weak signals'' DOA estimation based on RBFNN
基于RBF神经网络的弱信号DOA估计方法*

This paper proposed a novel intelligent technique for weak signals' DOA estimation in the presence of strong jamming or signal,which transfered the problem of DOA estimation into a large mount of data intelligent learning and recognition problem.Firstly,obtained the relationship between eigenvalue of the correlation matrix and signal power according to the signal subspace theory.Extracted the upper triangular half of the correlation matrix and the eigenvalue of the correlation matrix of knowing direction si...
