传统双站交叉定位精度较高,但在基线及其延长线无法定位且在基线附近定位误差迅速增大;预警机测高交叉定位可实现全空域定位,但定位精度不高。针对这两种定位方法的优缺点,提出了基于传统交叉定位和预警机测高交叉定位的距离解算加权融合算法,并进行了仿真分析比较,证实了算法的有效性。
The accuracy of pair-station for cross-locating is high,but the position error near pair-station's base line and extended line increases very quickly;and the ranging information from AEWS for cross-locating can locate the target in the whole airspace,but it's accuracy is not so high.So,based on the merits and faults of these two method,this paper conducts the research to the distance calculates weighting fusion model,carrying on the simulation analysis comparison.It demonstrated the effectiveness of the algorithm.
