A DOA Estimation Method Based on Biomimetic Pattern Recognition
基于仿生模式识别的DOA估计方法

In this paper, the applicability of biomimetic pattern recognition to information processing of abstract objects is studied, and then a DOA estimation method based on biomimetic pattern recognition is advanced. In this method, the output signals of antenna array are collected in practical conditions and expressed as feature vectors. These feature vectors are studied with the method of high dimensional geometry and the principle of biomimetic pattern recognition. By using the feature vectors as training samples ANN models are constructed. In our experiments, when SNR is 20dB or OdB, the correct estimation rate is 100%; when SNR is -20dB, the correct estimation rate is 83%. The experimental results show that the proposed method has the great advantage of preferably robust and fast computation.
