应用地磁场进行姿态测量是目前的研究热点,特别是将其应用于弹道修正弹上的,为滚转角的测量提供技术支持。通过在炮口加装人工磁场,为弹体滚转角的测量提供基准角,飞行过程中利用磁阻传感器敏感地磁场,获得弹体的实时滚转姿态。重点对滚转角测量方法的基本理论和工作原理进行了阐述,并对系统实现方案进行简单介绍,此系统可以实现滚转角的实时测量,且方法简单易行。

Attitude measurement based on magnetic field is a hot spot today and provides technology support for the roll angle measurement, especially in the application on trajectory correction projectiles. A method with the artificial magnetic field installed on gun muzzle was provided and it provides the reference angle for the roll attitude measurement of projectile. And the magnetoresistive sensors are used to measure the magnetic field to offer the roll attitude. The words pay more attention to the fundamental theory and operational principle of the roll attitude measurement, also the system design project. The system can give real-time roll attitude, and the measurement is simple and available.
