弹道导弹中段目标识别是中段反导作战的核心技术之一,也是反导指控系统指挥拦截作战的关键依据和成功拦截威胁弹头的保证。文中采用多特征综合模糊识别方法对中段多目标群进行识别研究,首先提取出具有明显物理意义的目标窄/宽带特征并对其进行模糊描述,在此基础上,对多目标进行综合模糊评判并给出评判准则,最后通过构建由三个目标组成的目标群开展仿真试验并给出仿真结果。结果表明,采用此方法能够快速准确的将真弹头从目标群中分离出来,具有较高的应用价值。

Target recognition in ballistic missile's midcourse is not only one of the key techniques of anti-BM in midcourse, but also the pivotal reference of command and control process and a guarantee of successful threatening warhead interception. The method of fuzzy recognition of multi-feature fusion was used to research target recognition in ballistic missile's midcourse. Firstly, a series of narrowband and wideband features with actual meanings were extracted and these features were described fuzzily. Based on these fuzzy features, multi-target fuzzy judgment was carried out and the rules of judgment were summarized. Finally, a group of targets including three targets was designed for simulation experiment and the result was given. The results show this method has better application value, which can separate real warhead from targets quickly and accurately.
