激光威胁信息模糊评估方法

Method of fuzzy evaluation on laser threat identification

激光威胁信息判别是对告警设备所传数据最基本的分析与处理,是激光对抗设备的核心技术,所得到的结果将作为干扰决策的依据,直接影响整个设备最终的工作效能。以激光告警设备为基础,基于获取的激光信号技术参数在确定威胁源时具有模糊性的特点,运用模糊推理理论,建立激光能量、波长、重复频率等技术参数的数学模型和激光威胁源识别的模糊决策规则库,提出了一种基于模糊推理的激光威胁源识别方法。其威胁评估的结果能够较准确地反映目标的威胁程度,为决策者提供稳定可信的决策依据。

Identification of laser threat information means the fundamental analysis and treatment of data transmitted from warning equipment. It is a key technology of laser counter equipment. And the results have direct influence on the final work efficiency of the whole system. According to the fuzzy characters of each laser parameter in confirming threat source, this paper establishs the fuzzy math models of laser energy, wavelength and repeat frequency and a fuzzy decision making rule library used for identifying laser threat source through the fuzzy inference theory; it also proposes a modified method of laser threat source identification based on fuzzy in- ference making. The arithmetic can improve the response speed and identify threat source nicely. And it provides the feasible evidence for the decision maker.
