一种通用的阵群目标队形识别方法

General formation recognition method for group targets

受传感器检测性能和观测噪声的影响,阵群成员位置观测集合往往具有不完全性和不确定性,并含有杂波。这种情况下,基于固定基准点的传统阵群目标队形识别方法不再适用。为此,提出了一种通用的阵群目标队形识别方法。该方法根据不同的队形模板和队形观测,动态选择二者队形描述的基准点,有效地抑制了漏检、位置噪声和杂波对阵群目标队形描述的影响;通过队形观测和队形模板的队形描述之间的匹配来对前者的队形进行识别。仿真实验验证了所提方法的有效性。

Influened by the detection performance and observation noise of a sensor,the position observation set of members within a group of targets is often incomplete and uncertain and usually contains clutter.The conventional group target formation recognition methods based on fixed datum mark are no more applicable on these practical conditions.Aiming at the problem,a general method for group target formation recognition is proposed.The method selects the datum mark dynamically depending on the different formation templates and formation observations,which restrains the effect of missing detection,position noise and clutter on the formation description for group targets effectively.The formation of the observed group target is recognized by matching of its formation description and that of the formation templates.Simulation experiments validate the effectiveness of the proposed method.
