摘　　要：异步融合是全局航迹融合时的普遍模式。现有的算法在进行异步融合时存在数据利用不充分、轨迹不精细的问题。文中提出的交替更新式异步融合算法,在保证融合精度的情况下,提供了全局航迹的精细轨迹。同时讨论了交替融合算法的应用问题。通过仿真,验证了交替异步融合的有效性。Asynchronous fusion is the general mode of global track fusion. Current algorithms have defects in not fully using all measurement data and not precisely describing the track. The alternative updating asynchronous fusion algorithm can provide refined track with guarantee of fusion precision. Some application problems of this algorithm Were also discussed. Through simulation, the validity of alternative asynchronous track fusion algorithm was proved.
