IMM模型组的选择与参数的设定

Selection of IMM’s Model Groups and Preferences

交互多模型中模型的确定直接影响到滤波跟踪的精度,通过比较典型单模型和不同模型组的交互多模型的性能,确定适合于所有运动状态的模型组。针对两坐标雷达获得的方位、距离信息,比较不同参数模型的跟踪精度,为模型组中的模型制定较为合理的参数。实际数据验证表明,所选择的模型组与设定的参数更适用于两坐标雷达对目标所有运动状态的跟踪滤波。

An Interacting Multiple Model （IMM） configuration which uses as it to build modules models affects tracking performance. In comparison of single model with IMM of different model groups, the best model groups of IMM were found out. Using azimuth and range acquired by two-dimensional radar, comparing tracking precision by different specific features of models, the appropriate specific features of IMM tracking filter were designed. Actual data results show that the determinate model groups and specific features are more appropriate to tracking most different movements for two-dimensional radar.
