| 摘 要： | 利用分形理论建立的海杂波模型具有巨大的潜力,在高频雷达海杂波多重分形特性的基础上建立了高频雷达海杂波的时域分形模型。通过对韦布尔分布、对数正态分布、瑞利分布和K分布4种最常用的海杂波的概率密度函数的比较分析并利用修正的Kolmogorov-Smirnov(K-S)统计检验,得出了高频雷达海杂波的时域模型具有先验的统计特性的结论,证明了新的海杂波时域分形模型的合理性,这对于高频雷达海杂波建模与仿真及其背景下目标检测研究具有现实意义。

| Abstract: | The model for radar sea clutter using fractal theory has potential application in many research fields.A new time domain fractal model for the sea clutter that based on the multifractal characteristics of HF sea clutter has been introduced.By using probability density function comparison analysis among 4 most commonly used distributions such as Weibull,Log Normal,Rayleigh and K distribution,and through a statistical test by modified Kolmogorov Smirnov(K-S),the conclusion of HF radar sea clutter bearing the ... |
