摘 要: | IMM算法只有在精确选取模型时才能取得良好的效果,本文采用一种新的"当前"Jerk模型(CS-Jerk模型)与匀速运动模型进行交互,讨论并证明了新的"当前"统计Jerk模型,即CS-Jerk模型对突发机动自适应跟踪性能好。仿真结果表明,在跟踪一般机动目标时,本文算法的误差和"当前"统计模型与CV模型交互的IMM算法相当;在跟踪突发机动目标时,其误差明显小于"当前"统计模型与CV交互的IMM算法。

Abstract: | Interacting Multiple Models(IMM) works well only when models were selected accurately.In this paper,a new IMM algorithm for tracking maneuvering target is proposed,by means of a new a current statistic Jerk model(CS-Jerk model) and a CV(Constant Velocity) model for interaction.Through analysis,the CS-Jerk model itself has a high precision when tracking abrupt maneuvering target.Simulation results show that,when there is only common maneuver the performance of the algorithm is the same with the IMM-CS-Jerk/CV,when there is a sudden maneuver,the performance of this algorithm is much better than the IMM-CS-Jerk/CV. |
