A Method to Localize Magnetic Target Based on a Seabed Array of Magnetometers

水中磁性目标的探测定位技术具有重要的军事价值。目前利用磁力仪阵列的磁性定位方法需要的采样点多,计算量大,实时性不强。为了更加实时有效地探测水中磁性目标,基于海底磁力仪阵列提出了一个新型磁性目标定位方法,方法包括海底磁力仪阵列的布控和定位计算两方面内容。该方法可以利用磁力仪阵列一组时间点数据实现水中磁性目标的定位计算,具有运算结构简单、实时性强等优点。并通过计算机仿真定量分析了磁力仪精度、磁力仪间隔距离等因素对定位误差的影响。

It has important martial value to localize the underwater magnetic target. Current magnetic localization method using a array of magnetometers needs a lot of samples and complicated calculations, and it is not real-time. In order to make a better real-time detection of underwater magnetic target efficiently, a new method to localize underwater magnetic target was proposed, which was based on a seabed array of magnetometers, and this method included arrange rnent of the seabed array of magnetometers and correlative calculations. This method can make use of a moment group of data of the array of magnetometers to localize the underwater magnetic target, and it has the virtue of simple operation structure and strong real-time. Several factors affecting the localization result such as the precision of magnetometer and the interval between magnetometers were analyzed by computer simulation.
