摘　　要：判别导引头对目标跟踪信息的可用性是双模制导系统中的关键环节。判别系统中引入置信度指标来描述跟踪信息的可用性。根据导引头探测环境复杂多变的特点,运用具有自主智能性的模糊逻辑推理系统对导引头跟踪信息的置信度进行判别,并针对模糊逻辑推理系统判别耗时问题,提出了把描述跟踪目标信息不确定性的模糊推理规则转化为神经网络的方法,实现了对导引头目标跟踪信息快速性、准确性的判别,满足了双模制导系统的要求。In this paper, the usability of seekers＇ measure information is denoted by introducing the confidence degree. The fuzzy logic reference system is designed based on expert knowledge database including various situations the seekers face. Taking the real time and precision requirements into account, a method of translating fuzzy inference rules into off-line trained neural network is put forward to solve the time-consuming problem of deciding the confidence degree of objective tracking information of the seekers in dual-mode guidance system. The validity of this method is proved by simulation.
