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 modern warfare, near space target will be an important method of long-distance attack in the future. The characters of near space targets make accurate tracking harder. In consideration of maneuverability and reentry character, a new tracking arithmetic is put forward in this paper, which combined with nonlinear 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.
