| 摘 要： | 通过对实测海杂波数据进行多重分形测度分析，判定海杂波信号具有多重分形特性。本文进一步提取表征海杂波复杂特性的多重分形参数，研究了不同条件下海杂波多重分形特性的变化特点，探讨了基于多重分形特性的雷达目标检测方法的可行性，并给出了实验结果。本文的研究为基于多重分形特性的海杂波建模与仿真、雷达目标检测提供了依据。

| Abstract: | By the multifractal measure analysis of the radar sea clutter, the sea clutter signal has multifractal properties. The multifractal parameters of the sea clutter are estimated and the difference of its multifractal properties under different conditions is studied. Finally, the feasibility to detect the target in the strong sea clutter by multifractal features is discussed, and experimental resutls are given. This study provides a basis for multifractal modeling and simulating of the sea cluter, and the target detection in the sea clutter by multifractal characteristics. |
