摘　　要：灵巧噪声干扰因兼有欺骗干扰和噪声干扰的特点,已成为1种干扰新体制雷达的有效样式,干扰识别也成为电子战领域研究的热点课题。针对卷积调制、数字多时延和间歇采样转发3种灵巧噪声干扰识别问题,通过分析干扰信号的产生机理和频谱特性,提出了1种基于盒维数特征的干扰识别方法。采用支持向量机进行分类识别,仿真验证了该方法具有较高的识别率。Smart noise jamming is a valid mode to interfere the new system radar,which has the characteristics of both de⁃ceiving jamming and noise jamming,and its recognition has become a hot topic in electronic warfare.Aiming at three kinds of smart noise jamming,which are the convolution modulation smart noise jamming,the digital multidelay smart noise jamming and the intermittent sampling repeater smart noise jamming,a method of smart noise jamming recognition based on box dimension is proposed by analyzing the generation principle and spectrum character.The support vector ma⁃chine is used to classify the jamming and the target.The simulation results show that this method has high recognition ac⁃curacy.
