基于多模型交互的红外目标跟踪方法研究

针对非线性运动的红外弱小目标跟踪问题，设计了一种基于交互式多模型性的跟踪方法。首先，引入多个运动模型，然后利用无迹卡尔曼滤波计算每个模型的滤波器状态估计，最后按照一定的概率加权得到总的状态估计值。使用数学仿真和物理实验对该方法进行了去噪和预测的功能验证，实验结果及相应理论分析表明该系统可有效的实现复杂背景下的红外弱小目标跟踪。

Research on infrared target tracking based on IMM

Aiming at the tracking problem of small infrared target doing non-linear action,a tracking method is designed based on IMM.Firstly,multi-motion-model is introduced;then the state estimate of each model is calculated by using unscented Kalman filter;finally the total state estimate value is got through certain probability.By means of mathematic simulation and physical experiment,the eliminating yawp and forecast function is tested,and the results shows that this system is effective to track small infrared target in complex context.
