摘要： 针对双屏电子篱笆系统在初轨确定前需要完成同一目标观测数据的数据关联问题,文章提出了一种计算形式简单且不依赖于循环迭代定轨计算径向速率的估值方法,并设计了相应的数据关联准则。仿真分析表明,这种数据关联准则与依赖定轨计算径向速率的关联方法相比,判别正确率相近,但计算时间不到后者的10%,算法的效率更高。

Abstract: The observation data association of the same object before computing the initial orbit is a crucial problem for the double fence radar system. An estimating Doppler velocity method was proposed, which was independent of initial orbit determination with iteration computation, and a corresponding data ssociation rule was designed. The simulation analysis shows that the exactness of the proposed data association rule is similar with that of the rule which is dependent on the Doppler velocity computed by the orbit determination, but the computing time is less than 10% of the latter one.
