摘要
文中提出了一种用于飞行姿态探测的磁通门式敏感组件,利用磁探头输出的感应电势中的偶次谐波幅值可以判断地磁场特性,给出了利用数字滤波及时域信号最优估计来提取有关偶次谐波幅值的数字信号分析方法,并通过仿真证明对于短序列磁通门探头的时域信号进行这样的处理切实可行。
In this paper,a attitude detecting system using fluxgate technique is put forward which can be used to detect the attitude of a flying body.It uses the pick-up second-harmonic amplitude component as the measure value for the M.F.A method of digital analysis is suggested which pick-up signal is processed using digital filter and optimum estimate in time domain.By simulating,the method has effected to processing short time sequence signal.
