摘要
为解决以往磁偶极子反演定位算法过度非线性化使得计算难度过大,以及非线性问题线性化后不易求得全局最优解等问题,提出了一种新的基于动磁测量技术(DMMT)的水下目标近场定位算法。该算法非线性化程度适中,具有多信息融合与数据快速处理的特点,试验验证该算法可实现动磁源的近场准确定位,且利用拟牛顿法(BFGS)可使计算简单易行。该算法可用于鱼雷近场定位,在水下探测、追踪、末弹道测绘等领域有重要用途。
In order to solve the problems that the excessive non-linearization of the previous magnetic dipole inversion algorithm makes the computation more difficulty and the global optimal solution is diffcult to obtain after linearization, a new kind of underwater target location algorithm based on dynamic magnetic measurement technology(CDMMT) is designed. The algorithm is moderately non-linear, with the features of multiple information fusion and fast data processing. The near-field accurate positioning of the dynamic magnetic source can be verified by experiments, and the quasi-Newton method( BFGS) can make the calculation simple and easy.The algorithm can be applied to the near-field positioning of torpedoes. It has important applications in underwater detection, tracking, surveying and mapping.
