Research on hypersonic target tracking algorithm in near space

针对临近空间高超声速飞行器运动特性,综述了交互多模型算法(IMM)相对单模型算法的优越性。以临近空间飞行器一个机动转弯部分轨迹进行仿真试验,仿真并分析了匀速(CV)、匀加速(CA)、Singer、当前统计(CS)、Jerk模型算法及IMM算法优点及局限性。结果表明,IMM算法跟踪机动目标在机动时稳定性、精度、机动适应性方面优于单模型算法,但存在实时性、模型转换可能性先验确定等问题,并针对这些问题提出可能的解决方法。

Aiming at the motion characteristics of the hypersonic vehicle in near space, the advantages of the relative single model algorithm is summarized. Simulation experiments are carried out, the characteristics and limitations of CV, CA, Singer, CS, Jerk model algorithm and IMM algorithm in the near space vehicle are analyzed. The results show that the IMM algorithm in tracking maneuvering target in maneuvering stability, precision, maneuvering adaptability is better than the single model algorithm, but there are these problems of real-time characteristics, model conversion prior possibility to determine, and possible solutions are proposed.
