摘　　要：基于鱼雷辐射电磁场测量方法,建立了磁矩测量误差的数学模型,并在此基础上利用MATLAB计算了各相关因素对测量误差的影响,提出了测量传感器尺寸和测量距离的选择原则,分析了磁矩测量误差与测量距离、传感器长度以及传感器直径的关系,得到了一定测量条件下测量误差相对于各因素的变化曲线,从而有助于选用合适的测量传感器尺寸和确定适当的测量位置,可以有效地减小磁矩测量的误差,旨在为鱼雷电磁场系统参数测量设备的设计提供参考。Based on the measuring method of torpedo radiant electromagnetic field, an error model for measuring the magnetic moment is set up. The influence of the relative factors on measurement error is calculated with the model via Matlab, and hence the selection principle of measuring sensor size and measured distance is presented. The relations of magnetic moment measurement error with measuring distance, sensor length and diameter are analyzed. Under the given measurement conditions, the curves of measurement error versus the above factors are obtained, which are helpful to determine the proper sensor diameter and measuring position, and therefore to reduce the measurement error of magnetic moment effectively. This research is expected to be a reference for the design of parameter measuring device for torpedo electromagnetic field.
