基于磁阻传感器的旋转弹飞行姿态测量方法

在弹体旋转的情况下，角速度陀螺测试滚转角误差较大，飞行姿态测量精度低。文中提出一种基于磁阻传感器代替滚转角速率陀螺，测量滚转弹飞行姿态的方法。通过仿真，基于磁阻传感器测量的姿态角比用滚转角速度陀螺测量的姿态角的精度提高了至少10倍，验证了该方法的可行性，同时也证明了该方法具有较高的精度。由于磁阻传感器成本较低，该方法具有广泛的推广和应用价值。

Getting the Attitude of a Rolling Airframe Missile Based on Magneto-resistive Sensor

The gyro will bring much error in measuring the roll angle of a rolling airframe missile,and the precision of the attitude is low.So it needs a new method to get the attitude of the rolling airframe missile.The article introduces a method to getting the attitude by magneto-resistive sensor instead of gyro.Through simulation we get the attitude by gyro and the attitude by magneto-resistive sensor,the attitude precision of the latter can be increased by 10 times than the front.It proves that the method is fea...
