分形噪声中的雷达目标检测方法

Radar ship targets detection based on the high order fractal feature

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分形特征——缝隙特征．分析了海杂波与目标回波的缝隙特征曲线，并结合模糊数学的有关理论进行了海杂波背景下的目标检测．仿真结果表明：利用缝隙特征进行雷达目标的检测。

The high order fractal feature is employed to analyze radar signals. The new fractal feature—lacunarity is used to identify the target and clutter. The lacunarity features of the sea clutter and target echo are analyzed. By combining the fuzzy theory with the lacunarity features, a new detection method is presented. Simulation results show that a higher accuracy of detection can be obtained by using the lacunarity feature than by fractal dimension.
