红外警戒系统中的数据互联算法

Data association algorithms for infrared surveillance systems

文中研究了舰载红外警戒系统中的多目标数据互联算法，提出了二维广义扇形相关波门及门限参数的设置方法和红外多目标跟踪中的粗、精互联准则。建立了航迹方位顺序号的概念，讨论了航迹信息的存贮及顺序号的转换方式，定义了用于最近邻准则的统计距离。

A multitarget tracking algorithm to the shipment infrared surveillance system is discussed in the paper. And the 2 D generalized sector correlation gate and setting of threshold parameters, the coarse and fine association criteria, and the concept of a track bearing sequence number are presented for the infrared multitarget tracking problem. The methods of track memory and sequence number transformation are shown, and the statistics distance for the nearest neighbor criterion is also defined. Finally the problems of track type transformation and association mass design are discussed.
