| 摘 要： | 提出运用IMM对目标进行跟踪时的航迹外推算法,解决了机动目标跟踪中的航迹外推问题。利用历史信息和转移概率推导出模型预测概率,结合单一模型的预测航迹和模型预测概率得到了相互作用多模型跟踪过程中的外推航迹。通过Monte-carlo仿真表明,运用外推方法在机动目标跟踪时能将误差控制在较小的范围内,具有很好的跟踪性能。

| Abstract: | An algorithm about flight path extrapolation during the target tracking with IMM is proposed.This algorithm solves the problem of the flight path extrapolation when the maneuvering target is being tracked.Based on the transition probability and history information,the model prediction probability is deduced,and then the extrapolation flight path during the target tracking with IMM is acquired in combination with the unimodal prediction flight path and model prediction probability. The result of Monte-Carlo simulation indicates that this algorithm can control the error in a small range when tracking a maneuvering target,so this algorithm has a good tracking performance. |
