| 摘 要： | 与惯性测量相比,用捷联安装在弹体上的磁阻式磁强计获取弹丸滚转姿态在带宽、体积、抗过载能力等方面都较有优势;不足的是,组成磁阻桥路的玻莫合金带温漂极大,致使传感器温度稳定性差,必须进行动态补偿,文中提出一种硬件补偿方法,仿真和实验均证实了该方法的可行性。

| Abstract: | Magnetometers are light-weighted,rigid,and reliable detector with high overload tolerance comparing with inertial sensors.A significant drawback in magnetometer application is the temperature drifts.A dynamic hardware correction method is derived in this paper.The simulation and experiments results are carried out.It is proved that the low-cost hardware correction circuit is effective and accurate. |
