一种三维交叉定位的优化求解

摘要

The principle for 3D bearings only location is studied in this paper, the process of getting the values in x-y plane and the altitude for 3D bearings only location is given. In fact, the bearings can not cross to one dot due to the random measure errors, so to estimate the errors, and make the bearings cross close to the best of it abilities, we can get optimizing location. Finally the PSO is introduced to solve the optimization; the result demonstrates the capability and effectiveness of the algorithm.%论文分析了三维交叉定位的原理,给出传统三维交叉定位分解到二维和一维的计算过程.由于测量随机误差的存在,三维交叉并不能直正交于一点,那么通过误差估计,使其尽可能最优地交于一点,即可实现三维交叉定位的优化求解.最后通过粒子优化算法对求解进行了实现,结果表明该方法可行,具有一定应用价值.
