摘要
研究了基于交互式多模型(IMM)的低小慢目标跟踪问题。基于低小慢目标运动特征的分析,以及目标匀速(CV)直线、匀加速(CA)直线、曲线飞行航迹模型,给出了目标跟踪的IMM算法及其流程。仿真结果表明:该算法能稳定精确跟踪低空目标。
The tracking of low altitude small slow target based on interacting multiple model （IMM） was studied in this paper. The algorithm and its flowchart were given out according to the analysis of the flying characteristics of low altitude small slow target and the three models which were rectilinear motion at constant velocity, rectilinear motion at constant acceleration and curvilinear motion. The simulation results showed that this algorithm could track the low altitude target with high accuracy stably.
