利用地球磁场进行弹丸飞行姿态的测试

摘要

研究了基于地磁场测试弹丸姿态的工作原理和测试方法;建立了使用地磁传感器测试弹丸姿态的数学模型;给出了某弹丸姿态的实测曲线;提出了地磁传感器实际测试中需要注意的问题,给出了解决这些问题的方法.%The measuring principle and measuring methods of the projectile attitude based on geomagnetic field is proposed. The mathematical model of the projectile attitude are derived. The measured curve of the attitude projectile are introduced. Put forward the problems that need attention in the projectile spin speed test and gives specific ways to solve these problems.
