| 摘 要： | 本文将高阶分形特征用于雷达信号的分析,提取出用于区分目标和杂波的新的分形特征——缝隙尺度变化率.推导了缝隙值在加性分形噪声中的关系式.实验表明:利用缝隙特征进行海上雷达目标的检测,可以取得较分维值检测更高的准确率.

| Abstract: | In this paper,the high order fractal feature is employed to analyze radar signal.The new fractal feature lacunarity is used to identify target and clutter.We derive formula of lacunarity in additive noise.The experiments show that higher detection accuracy of sea surface targets can be obtained by using lacunarity feature than by fractal dimension. |
