摘要:

对于三维多站测向定位,给出了一种利用数据融合方法处理多站交会测量结果的定位方法。该方法首先在n个观测站中任取两站计算得交会结果,再引入一种加权运算,对两站交会结果进行融合,得到一种新的定位方法,最后进行仿真和性能分析。仿真结果表明,新算法提高了定位精度,避免了迭代初值的选取,保证了定位方法的有效性并减小了工作量。

Abstract:

A new data fusion approach is given for the 3-D multi-station measurements.This method first picks two stations in n observation stations to gain a rendezvous result,then introduces one kind of weighting operation to fuse the two station rendezvous results and obtains a new localization method.Finally simulation and performance analysis are carried out.The simulation result indicates that the new algorithm increases the localization precision,avoids the iterative starting value selection,guarantees the localization method's validity and reduces the work load.
