临近空间目标运动建模与跟踪方法研究

x-43、x-5l等临近空间高超声速飞行器的相继出现，给雷达目标跟踪提出了新的挑战，临近空间高超声速飞行器具有高速度、高机动的特点，常规跟踪算法跟踪性能低，不能满足作战使用要求。本文通过分析临近空间高超声速飞行器的运动特性，建立临近空间飞行器的运动模型，阐述临近空间目标跟踪的技术难点，提出了交互多模型的临近空间飞行器跟踪的方法，并对该算法进行了仿真验证，与传统的跟踪算法比较，该算法的跟踪精度有明显提高。

Study on Modeling of Near - space Moving Targets and its Tracking Algorithm

As emergence of Near-space hypersonic aircrafts such as X-43, X-51 in progression, new challenges to the target tracking techniques are raised. Since the near-space hypersonic aircrafts have characteristics of high speed and high maneuverability, and the conventional tracking algorithm has low tracking capability; it cannot sat- isfy operational requirements. The motion-model of near-space aircraft is set up by analyzing near-space hypersonic aircrafts ; and technical difficulties of tracking hypersonic targets in near space is depicted ; an algorithm of tracking near-space hypersonic aircrafts with interactive multi-model is presented, which is simulated and verified. Compa- ring with the conventional tracking algorithm, the tracking accuracy of this algorithm is increased distinctively.
