摘要
目前所研究的离线磁定位是在目标舰船长度和模型结构已知的前提下进行的,且未能对定位结果作出真伪判断。在目标舰船长度、运动参数、磁探头姿态角均未知的情况下,设计了一种基于偶极子个数可变的非固定混合模型结构的离线磁定位算法,以舰船长度估计解的连续性作为判断真伪的条件,计算结果表明,该算法定位精确、判断可靠。
Now all the study on offline magnetic localization is based on the knowning of the length of target and the model＂ structure. But it can＇t judge the right of localization outcome. Based on the changeable number of dipole mixed magnetic model, a offline magnetic locatization algorithm is developed to work out warship＇s length, warship＇s position and attitude of magnetic sensor and etc. It uses the concatenation outcome of warship＇s length and looks stable resolution as correct one.
