Spatial Spectrum Estimation Method of Flank Twin-line Array Based on Cross-spectrum Correlation

Li Zhizhong;Wang Sen;Xu Zhongliang;Dai Weiguo;Liu Qijun;Navy Submarine Academy;PLA 91154;  
Considering the structural features of the flank twin-line array, researches on spatial spectrum estimation of twin-line array based on adaptive beam-forming and cross-spectrum correlation were carried out. A spatial spectrum estimation method based on cross-spectrum correlation is proposed according to the theory of cross-spectrum. The study of spectrum estimation performance comparison of the twin-line array was finished by that method combined with the conventional beam-forming and the adaptive beam-forming respectively. The results prove that the method based on cross-spectrum correlation has a better capability in noise suppression; and the method, which combined adaptive beam-forming with cross-spectrum correlation, is the best fit for spatial spectrum estimation of the flank twin-line array.
