通过对临近空间高超声速飞行器的受力分析,建立了其周期性跳跃运动的数学模型,仿真分析了其运动特性；提出了一种加速度均匀变化的运动模型(constant differential of acceleration,CDA),并与CV模型、CA模型交互,使用引入强跟踪滤波器的交互式多模型算法对周期性跳跃运动进行跟踪研究。结果表明,该跟踪算法比经典IMM算法有更好的跟踪精度。

Through force analysis on hypersonic vehicle, the motion model of periodic skip trajectory established, and through simulation periodic skip trajectory is analyzed. Then constant differential of acceleration ( CDA) model is introduced, and strong tracking filter ( STF) method is introduced into IMM algorithm. Research is done into tracking the periodic skip trajectory with the newly put forward algorithm. Simulations show that the new method has better tracking performance.
