| 摘 要： | 为进行铁磁目标磁场的精确建模,利用磁传感器阵列测量了铁磁目标周围特定区域的磁场分布,根据测量数据重建铁磁目标的磁源分布,并以观测矩阵的奇异值坡度为评价标准对磁传感器阵列所获得的铁磁目标磁场信息量进行评估。通过将理想和简化布置形式下的磁传感器三分量阵列和垂直分量阵列进行对比分析,发现与垂直分量阵列相比,三分量阵列更具优势,而简化三分量阵列则因其具有可获得充分的磁场信息、能减少测量点数、占地最小等优点成为实际工程中最可取的阵列形式。 |

| Abstract: | To accurately model the magnetic fields of ferromagnetic objects,we measured the magnetic fields around ferromagnetic objects,and reconstructed the magnetic sources in the objects.Based on the slope of the singular values as the evaluation criterion,the information content from the magnetic sensor array for the ferromagnetic object was evaluated.The triaxial and normal-axial sensor arrays with ideal and reduced arrangements are compared,and the triaxial sensor array shows better performance than that of normal-axial sensor array.The reduced triaxial array is the best practicable arrangement with the maximum information content,the lesser measuring points,and the minimum space occupation. |
| Keywords: | magnetic fields of magnetic object magnetic sensor array evaluation criterion inverse modeling |
