针对利用磁体模拟法进行低磁类舰船内外磁场换算时，方程离散后容易呈现病态的问题，根据内部测量数据的变化趋势，提出了一种先限定某些位置作为优化测量点，再利用微粒群算法优化其它的优化位置的方法。不但解决了测量位置优化问题，而且需要的测量点数较少。通过两组不同测量位置的磁场推算实例，验证了优化位置的有效性，其推算精度符合工程实际需求。

Aiming at the problem that the condition number of coefficient matrix is very large after the equation diseretization when ex- trapolating the low magnetic ship~ s magnetic field, a new method was introduced based on the discuss about the contribution of some points to onboard data. It can get some optimal measurement positions from these points that are most important for magnetic field extrapolation,and then get others thanks to particle swarm optimization algorithm. The new method not only optimizes the positions, but also reduces the num- ber of points. The position has been validated by an experiment. The good results explain that the conclusion is reasonable.
