改进模糊算法在雷达辐射源识别中的应用

Application of Improved Fuzzy Algorithm in Radar Emitter Identification

要赢得现代战争的主动权，就必须充分掌握敌方雷达辐射源的信息，这就使得雷达辐射源识别成为现代电子侦察系统中最重要的功能模块之一。首先概述了雷达辐射源识别的基本思想、识别系统和常见识别算法，然后介绍了模糊识别理论。针对当前辐射源识别存在的模糊性和不确定性特点，改进了辐射源模糊识别算法，详细描述了算法的实现过程，最后阐述了算法的实例应用。结果表明，相比于模糊识别算法，改进算法的正确识别率有了明显提高。

To obtain the dominance of the modem warfare, it is important to acquire information of hostile radar emitter identification （EI） fully, which makes radar EI to be one of the most important modules in modem electronic systems. In this paper, the basic idea of radar EI, identification systems and familiar identification algorithms are summarized. Then, the fuzzy identification theory is introduced. Aimed at the characteristic of fuzziness and uncertainty in present EI, the EI algorithm based on fuzzy theory is improved, and the realization process of the algorithm is described in detail, finally the algorithm＇s instance application is expatiated. The experiment result shows that the improved algorithm identification rate enhances evidently compared with fuzzy identification algorithm.
