群目标等效量测形成算法研究

Study on Equivalent Measurement Forming Method About Group-target

群目标作为多目标的一种特殊形式，实现跟踪的关键问题之一是要得到对其的等效量测。为此，提出了形成群目标等效量测几何中心、质心和重心的3种方法。给出了求解群目标几何中心、质心和重心的算法；阐述了以群目标几何中心、质心和重心为等效量测的跟踪原理和适用范围；得出了3种算法均能有效地形成群目标的等效量测，且适用于不同战术环境的结论。

Group-target is a special form of multi-targets. One of the key problems to realize group-target tracking is getting its equivalent measurement. Three methods to get its equivalent are proposed in this paper, which are getting its geometry, centroid and barycenter. The process and methods to compute group-target＇s geometry center, centroid and barycenter are also presented. Then, the tracking principle and using field are explained for group-target＇s geometry, centroid and baryeenter as equivalent measurement. By comparing, the result shows that these three methods all can get group-target＇s equivalent measurement, and they may be applied in different tactics background.
