摘　　要：为有效解决现有磁性定位方法定位精度不高的问题,提出了基于磁偶极子阵列模型的磁定位方法。为求解模型参数,根据磁场测量数据建立了定位参数反演模型。针对实际舰船磁性检测中所得磁场信息的局部性而引起反演模型病态不适定问题,应用Tikhonov正则化方法优化求解模型参数。船模实验证明,该方法对船模进行定位计算,定位精度高,结果稳定可靠。In order to effectively overcome the difficulties ,which the location accuracy is not high in current location methods, this paper presents magnetic loation method based on magnetic dipoles array model. In order to solve the model parameter, establish the location parameter inverse model based on measured data. Due to lack of the enough measured physical information method,the inverse model is always ill posed. This inverse problem is solved by Tikhonov regularization method. The ship model experiment shows that the location aecurary is high ,and the result is stable and reliable.
