摘要
X-43、X-51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。
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.
