本文研究了强杂波干扰背景下运用模糊集合理论解决高分辨雷达信号的检测问题。文中首先分析了在高分辨雷达体制下获取稳定距离像的方法，并指出了传统匹配滤波方法的局限性。针对该问题，文中定义了四种模糊集合相似性测度，并在此基础上提出了一种模糊匹配滤波方法。基于文中定义的增量相似性测度准则对平均距离像采用模糊匹配滤波，实验结果表明该方法具有在强干扰背景下检测目标的良好能力，其性能明显优于传统匹配滤波方法。
This paper studies the detection of high resolution radar signals using the theory of fuzzy sets in the context of strong clutter interference. Firstly, the paper analyzes the method of obtaining stable distance image under high-resolution radar system and points out the limitations of the traditional matched filtering method. In order to solve this problem, four similarity measures of fuzzy sets are defined, and based on which, a fuzzy matched filtering method is proposed. Based on the incremental similarity measure criterion defined in this paper, fuzzy matching filtering is applied to the average distance image. The experimental results show that this method has the good ability to detect the target under the strong interference background and its performance is obviously better than the traditional matched filtering method.
