纯方位目标跟踪中的观测器机动优化研究和如何实现的方法(2)-Bearings-only Target Tracking mobile optimization of observer and how to implement the method (2)

A novel fault feature extraction method based on the local mean decomposition technology and multi-scale entropy is proposed in this paper. When fault occurs in roller bearings, the vibration signals picked up would exactly display non-stationary
