| 摘 要： | 多重分形维数是单个分形维数的扩展,高阶分形特性缝隙则是分形维数的一个补充。文章研究了不同调制方式雷达辐射源信号的多重分形熵和缝隙尺寸变化率,研究结果表明不同调制信号的多重分形熵和缝隙尺寸变化率是不同的,因此它们可在雷达信号调制方式的分类识别中作为特征参数。并由仿真结果验证了基于多重分形熵和缝隙尺寸变化率进行的分类具有较高的识别率。

| Abstract: | Multifractal dimension is the expansion of single fractal dimension,and high-order fractal feature lacunarity is the complement of fractal dimension.The paper studies the multifractal entropy and lacunarity measure variation rate of different modulation radar emitter signal,and the study results indicate that different modulation signal has different multifractal entropy and lacunarity measure variation rate,therefore they can be as the feature parameters in the classification and recognition of radar signa... |
