| 摘 要： | 为克服海杂波分形维数值估计需要较长的数据长度的缺陷,提出了基于扫描间积累的分形维数值估计方法.首先研究了几种常用的分维值估计方法,从分维值的定义出发证明了分段分维估计方法与连续数据估计方法的等价性,然后通过迭代算法求得分形维数估计值.仿真结果表明提出的方法降低了对雷达驻留时间的要求,并且具有较小的运算量,提高了微弱目标的检测性能.该方法可以用于岸基对海雷达检测海表面微弱目标.

| Abstract: | Considering the problem that long data series is needed in sea clutter fractal dimension estimation,we proposed a fractal dimension estimation method based on accumulation between scans.First,a few fractal dimension estimation methods are introduced,and the equivalence between subsection fractal dimension estimation method and continued series estimation method was demonstrated.Then the fractal dimension value was obtained by using iterated algorithm.Experiments results show that the proposed method reduces... |
