两种VSMM机动目标跟踪算法的比较

摘要

比较了两种基于变结构多模型的机动目标跟踪方法。一种算法采用匀速模型和“当前”统计模型组成的模型集进行交互，另一种算法采用匀速模型和转弯模型组成的模型集进行交互，两种算法分别通过对机动频率自适应估计和实时估计转弯角速度，实现了模型集的自适应。通过仿真，对这两种算法的跟踪精度和计算量进行了分析比较，指出了其适用场合。%Two maneuvering target tracking multiple-model algorithms which based on variable structure are compared in this paper. One algorithm adopts CV model and CS model for interaction,the other one adopts CV model and CT model for interaction,and realizes the adaptive of model sets by adjusting the maneuvering frequency parameter and the angular acceleration in real-time separately. Through simulating,this two algorithms in terms of the accuracy of tracking and the amount of computation are analyzed and compared,and the occasion of their application is pointed out.
