摘　　要：辐射源识别是雷达电子战的重要领域，辐射源个体识别技术因其精确性受到越来越多的关注。雷达脉冲的包络含有辐射源的个体信息，可以用作辐射源个体识别。文章首先定义了Holder系数，然后提出了基于脉冲上升／下降沿的Holder系数特征提取算法，最后验证了Holder系数特征集的稳定性和有效性。理论分析和实验结果表明了基于脉冲上升／下降沿的Holder系数特征提取算法对噪声不敏感，可以完成雷达辐射源的个体识别。不同p、q值的组合为工程应用提供更多的选择。Emitter recognition is important to the radar warfare. With the development of the radar individual recognition technique, it has to be the focus technique in this area. The envelope of the radar pulse can be used to identify the different radar emitter individually because it contains the special information. In this paper, the definition of Holder coefficient is given firstly. Then, the Holder coefficient feature extraction algorithm based on rising/falling edge is described and the features set is formed. Finally, the experiment results prove its stability and validity, and not sensitive to noise. Meanwhile Holder coefficient takes different types, which provides several useful choices for engineering.
