摘　　要：双磁芯磁通门式传感器作为消磁电流控制系统中的控制元件,其磁对称性直接影响消磁系统的零场输出误差及控制误差,对此提出了一种双磁芯磁通门式传感器磁对称性的频谱分析方法。该分析方法根据双磁芯磁通门式传感器的工作频率特性,通过对消磁系统控制信号的频谱分析,评估磁传感器的磁对称性能。实验证明,该分析方法能够较准确地评估双磁芯磁通门式传感器的磁对称性能,评估结果能作为消磁系统控制误差的分析依据,具有实用性及可行性。Dual magnetic core fluxgate magnetometer is the control element of the degaussing current control system.The magnetic symmetry of the magnetometerwould directly influence the zero-field output error and the control error of the degaussing system.So the spectrum analysis method for the magnetic symmetry of the dual magnetic core fluxgate magnetometer was proposed.The analysis method could appraise the sensor′s magnetic symmetry based on the operating frequency characteristics of the fluxgate sensor and the spectrum analysis of the degaussing control signal.The experiments show the proposed method could appraise the magnetic symmetry of dual magnetic core fluxgate sensor,and the appraising results could refer to the error analysis of the degaussing control system.The method is practical and feasible.
