摘　　要：随着高超声速武器技术的日趋成熟,临近空间目标飞行器已成为未来远程打击的重要手段,这对临近空间目标的精确跟踪提出了更高的要求。文中根据临空目标的特性,考虑机动性及再入特性,结合非线性估计技术,提出了一种新的跟踪模型,仿真结果表明,该跟踪模型能够全程有效跟踪临空目标,跟踪精度优于Singer模型及二体运动模型。With the technology of hypersonic weapon in-depth development in modem warfare, near space target will be an impor- tant method of long-distance attack in the future. The characters of near space targets make accurate tracking harder. In considera- tion of maneuverability and reentry character, a new tracking arithmetic is put forward in this paper, which combined with nonlin- ear estimation theory. Experiments are done to prove the effectiveness of the new tracking algorithm, and the tracking precision is higher than Singer algorithm or two body motion algorithm.
