摘　　要：针对磁传感器测量信号滤波处理及其引入的误差,提出了抗强磁干扰滤波器及相移补偿方法。该滤波方法是针对地磁测量系统从信号的时域特性出发的处理方法,在有效保持有用的微弱的地磁信号的同时,还具有计算简单、应用方便的特点。仿真验证表明,该相移补偿方法有效地消除了原始信号与滤波后信号之间的相位误差,保证了解算精度。A phase delay compensation methoed of anti-strong magnetic interference filter was proposed to solve the problem of the magnetic sensor measurement error caused by filter.The methoed was based on geomagnetic measurement system in time domain.It promise the weak magnetic signal that could be used effectively,simply and conveniently.Simulation results showed that the phase delay compensation model could effectively remove the error between the original signal and the filtered signals,ensure the accuracy of the calculation.
