三轴磁传感器运动噪声消除方法

Motion Noise Elimination Method of Three-axis Magnetic Sensor

论文通过对三轴磁传感器运动噪声的产生机理理论分析,找到了噪声产生的原因:三轴磁引信接收器的三个轴并不理想正交;三轴灵敏度不完全一致;接收器电路存在有漂移、噪声;接收器铁芯存在剩磁。给出了消除噪声的方法,并通过实验验证了方法的有效性。

In this paper,through the theoretical analysis of the mechanism of the motion noise of the three-axis magnetic sensor,the causes of the noise are found:the three axes of the three-axis magnetic fuze receiver are not ideal orthogonal,the sensitivity of the three-axis is not completely consistent,the circuit of the receiver has drift and noise,the core of the receiver has remanence.The method of noise eimination is given,and the effectiveness of the method is verified by experiments.
