摘　　要：磁异常探测在反潜探测、未爆弹(UXO)探测中广泛应用。随着探测需求趋于高精度与定量化,利用磁异常探测实现对隐蔽目标的精确定位成为当下焦点课题。研究指出传统利用磁异常信号识别的方法难以准确定位目标,难以确定目标位于测线的左侧或右侧,通常将目标定位于测线所在的强磁异常区,因此当目标位于测线左侧或者右侧时,定位结果发生偏差。磁异常三维成像可以得到异常体的水平位置以及深度,能够为隐蔽目标高精度定位提供依据。基于磁异常三维成像,通过仿真模拟和实例应用讨论三维反演对隐蔽目标的定位能力。研究表明:三维成像能够在测点距较大的情况下精确定位隐蔽目标的三维空间分布,能够为磁异探测中隐蔽目标的精确定位提供技术支撑。Magnetic anomaly detection is extensively utilized in anti-submarine warfare and the detection of unexploded ordnance(UXO).With increasing demands for higher precision and quantification in detection,precise localization of covert targets using magnetic anomaly detection has emerged as a critical area of focus.Traditional methods,which rely solely on magnetic anomaly signals for target recognition,often fail to accurately determine the target's position,making it difficult to ascertain whether the target is located directly beneath,to the left,or to the right of the survey line.Three-dimensional imaging,however,can ascertain both the horizontal position and depth of an anomaly,thus facilitating high-precision localization of covert targets.Based on magnetic anomaly three-dimensional imaging,the effectiveness of three-dimensional inversion for target localization is discussed through both simulation models and practical applications.The research demonstrates that three-dimensional imaging can precisely map the three-dimensional spatial distribution of covert targets,even at significant distances between measurement points,thereby providing robust technical support for accurate localization of covert targets in magnetic anomaly detection.
