弹道中段目标的融合识别

Research on target recognition in the middle part of the ballistic trajectory

针对弹道中段目标识别时间资源有限的问题,提出了一种基于识别手段可信度增长的融合识别新算法。首先给出了识别可信度的定义及其增长模型,并分析了识别可信度增长模型对识别时间的影响,继而运用D-S证据推理方法得到了基于识别可信度增长的融合识别算法。仿真实例表明,该算法可以缩短识别时间,提高识别效率。

To solve the limited-time-sources problem of target recognition in the middle part of the ballistic trajectory, a new algorithm based on Dempster-Shafer＇s theory is studied by considering the increasing credibility of the target recognition approach. Firstly, the definition of the credibility of the target recognition approach is given. Secondly, a fusion formula considering the increasing credibility is derived. Simulation is given to show the effect of the algorithm.
