一种新的机动目标跟踪算法

针对反舰导弹末端超音速、跃升俯冲的攻击模式,提出了一种基于描述导弹受力状态和运动参数之间关系的模型的机动目标跟踪新算法,可以通过在线辨识模型中的力学参数,自动适应导弹运动模态的变化,最后研究了新算法与基于CV、CA模型的目标跟踪算法的性能比较。仿真结果表明,在反舰导弹末端超音速、跃升俯冲攻击模式下,基于CV、CA模型的目标跟踪算法性能较差,而新算法可显著提高对高速强机动目标的跟踪性能。

New Algorithm for Maneuvering Target Tracking

Aiming at the anti-ship missile's endmost attacking mode of rising and swooping ultrasonically, a new algorithm for maneuvering target tracking was proposed based on the model describing the relation between the dynamics and the kinematics of missile, which could automatically adapt to variety of the missile's moving mode by identifying the dynamics characters. Then the performance of the new algorithm was compared with algorithms for target tracking based on CV and CA. The simulation results show that the performance of algorithm for target tracking based on CV or CA is low in the anti-ship missile's endmost attacking mode of rising and swooping ultrasonically, but the new algorithm can distinctly improve the performance of tracking high speed and strong maneuvering targets.
