基于只测向的机载单站定位技术

Airborne single-station passive location technology only based on bearing method

针对机载单站无源交叉定位技术中存在的虚假定位问题,提出一种新的关联方法.该算法先通过异面测向线距离进行测向粗关联,排除大部分虚假定位组合,减小运算量.再利用基于不变量的关联方法进行测向细关联,近一步排除虚假测向组合,提取出真实目标的测向线组合进行交叉定位.实验结果表明,文中算法可以满足三维空间下对目标准确、快速的定位需求.

In this paper, a new association method is proposed to tackle the false location problem of passive cross location technology in airborne single station. This algorithm first performs rough data association by using bearing line distances on different surfaces to eliminate most false location combinations, thus reducing the amount of computation. Next the algorithm will carry out fine association by using invariant-based correlation method to further exclude false bearing line combinations and extract real bearing line combinations of target for cross location. Experimental results show that the proposed algorithm can meet the need for accurate and quick target location in three-dimensional space.
