| 摘 要： | 基于两台经纬仪交会测量原理,分析了两台经纬仪交会测量误差;提出了四台经纬仪两两交会测量结果的加权融合处理方法,该方法充分利用了所有测站的测量信息,而且融合测量值误差小于任两台经纬仪的交会误差;最后进行了仿真分析.从仿真结果可以看出,利用该方法可以大大提高空中目标的辨识精度.另外,本方法同样适用于三台或三台以上经纬仪的交会测量问题.

| Abstract: | The positioning errors are analyzied for aerial targets by two theodolites.A data fusion method is presented on four theodolites by intersection.This method makes good use of all gained informations and its positioning errors are less than these by any two theodolites.Last,Simulation is made.The result shows that this method is very efficient and can improve identify precision for aerial targets.The above method can be applyed to three or more theodolites. |
