摘　　要：磁场异常探测是隐蔽目标探测领域一项重要的探测技术,磁传感器技术的进步促使磁矢量探测成为当前热点。然而有关矢量磁异常的目标定量探测方法讨论较少,关于磁矢量探测与磁标量探测的差异性众说不一,存在巨大争论。基于矢量磁异常三维成像的隐蔽目标精确探测方法,讨论磁标量探测与矢量探测的差异性,并通过仿真实验与实际案例讨论了矢量磁异常的探测效能。研究表明:矢量磁异常三维成像能够更准确地探测隐蔽目标的三维空间分布与目标磁性特征,能够为隐蔽目标位置圈定以及目标类型识别提供依据。Magnetic anomaly detection(MAD)is an important detection technology in the field of covert target detection.The progress of magnetic sensor technology makes vector magnetic detection become a hot spot all over the world.However,there are few discussions about quantitative detection methods of vector magnetic anomaly,and there still is a huge debate on the differences between vector magnetic detection and scalar detection.In this paper,a covert target detection method based on 3D imaging of vector magnetic anomaly is applied to discuss the differences between scalar magnetic detection and vector magnetic detection.The detection efficiency of vector magnetic anomaly is discussed through simulation experiments and field application.The study shows that 3D imaging of vector magnetic anomaly can detect 3D spatial distribution and magnetic characteristics of covert targets more accurately,which can provide a powerful strategy for target location and identification.
