摘　　要：飞行器、舰船和潜艇等典型可移动平台具有复杂的磁场,获取这些磁场信息对于提高磁场探测精度具有重要意义。文章在简要总结典型可移动平台复杂磁场的建模方法基础上,结合卫星自身特点,提出基于多偶极子磁性模型的卫星复杂磁场快速建模方法。其技术途径有两种:一是基于单机磁试验数据建立单机磁性模型,再组合成整星多偶极子磁性模型;二是基于卫星磁试验数据直接建立整星多偶极子磁性模型。采用这两种技术途径完成某型号卫星的磁场建模、计算与测量验证,测试结果表明多偶极子法可很好地适用于磁洁净卫星复杂磁场的快速建模计算,精度优于0.2 nT。Typical movable platforms such as aircrafts,ships,and submarines have complex magnetic fields.It is significant to obtain the magnetic field information for improving the magnetic field detection accuracy.Based on a brief summary of methods for modeling complex magnetic fields of these platforms,and taking into account the characteristics of satellites,a method for modeling the complex magnetic fields of satellite based on the multi-dipole magnetic model was proposed in this paper.There are two technical approaches:One was to create a single-machine magnetic model based on the single-machine magnetic test data and then combine all the models into a whole-satellite multi-dipole magnetic model;the other was to directly construct the multi-dipole magnetic model based on the test data of satellite magnetic.The magnetic field modeling,calculation and measurement verification of a satellite have been completed along the two technical paths above.The results show that the multi-dipole method is suitable for the rapid magnetic modeling and calculation of complex magnetic fields of the magnetic clean satellite with an accuracy of better than 0.2 nT.
