3) attitude signal
姿态信号
1.
In order to resolve the problem of dynamic attitude measurement,a kind of dynamic attitude signal filtering method based on empirical mode decomposition(EMD) was proposed.
为了解决火炮动态姿态测量问题,提出了基于经验模态分解(EMD)的动态姿态信号滤波方法,将非平稳信号分解为不同特征尺度上的分段固有模态函数(IMF),而这些IMF体现了信号能量在时间、空间等各种尺度上的分布规律,从而构造了时间尺度滤波,从分解后的各IMF中Hilbert谱分析寻找有用的信息,结合信号ⅡR数字滤波技术进行重构来消除信号中的干扰,实时获得真实姿态角。
