摘要
地磁场的强度和方向是地理位置的函数,可通过对地磁矢量的探测确定稳定飞行的弹体在空中的滚转姿态。但在利用地磁探测滚转姿态的过程中,存在着诸如地磁异常、地磁传感器的使用域等问题,在地磁探测中这些问题应该得到考虑。文中主要针对影响姿态探测可行性的几种情况,初步分析了影响地磁参量的原因,讨论了影响的程度,提出了一些相应的措施。
The intensity and direction of the geomagnetism vector is a function of geographical position. The roll attitude of a flying body can be calculated by detecting geomagnetism. In the course of detecting the roll attitude by means of geomagnetism, some problems such as geomagnetism abnormity, the usage limit of the geomagnetism sensor must be taken into account. In this paper, some causes and extent of impacting geomagnetism parameter are analyzed, and the correlative measure is put forward.
