【摘要】 目的开发一个实用的目标跟踪方法，它对机动目标和非机动目标的跟踪精度都很高．方法首先建立新IMM跟踪模型，然后用计算机仿真的方法证实该模型的性能，并与已有的经常用于机动目标跟踪的“当前”加速度模型比较．结果仿真结果表明，IMM模型在目标运动的非机动段的跟踪精度比“当前”加速度模型高得多，而在机动段则有着与“当前”加速度模型相当的精度．结论在目标跟踪时，IMM模型比“当前”加速度模型有更高的综合精度，它将发展成为一种实用目标跟踪方法．更多还原

【Abstract】 Aim To develop a practical target tracking algorithm for different motion modes. Methods After creation of the new model, it was implemented by computer simulation to prove its performance and compared with the often-used current statistical model. Results The simulation results show that the new IMM (interactive multiple model) have low tracking error in both maneuVering segment and non~Inaneuwi segment while the current statistical model bas muCh higher tracking error in non-maneuvering segment. Conclusion In the point of trackintaccuracy, the new IMM method is much better than the current acceleration method. It can develop into a practical target hacking method.更多还原
