基于神经网络的舰船姿态信息谱估计方法

A Method of Spectral Analysis Based on ANN for Ship Attitude Signal

从最大熵谱估计入手，用TH网络实时地实现了对船用惯导系统姿态测量信号的最大熵一维谱估计。研究表明，由于神经网络的高度运算能力，该方法有效地解决了信号频谱处理过程中处理性能与运算量之间的矛盾，为现代谱估计提供了新途径。

Based on the theory of maximum entropy spectral analysis ,a linear program neural network (TH Neural Network)is proposed in this paper ,which is used to analyse the attitude signal spectral for marine inertial navigation system.It is shown that owing to the high calculation ability of the ANN,this method is effective in solving the contradiction between the performance and the calculation volume in analysing signal spectral,and it supplies a new way for modern spectral analysis.
