| 摘 要： | 该文提出一种基于长相关特征的海上目标检测方法。利用半方差函数，建立海杂波在时间轴上的长相关特征曲线。根据所获得的曲线特征，分别提出半方差曲线拟合斜率和半方差曲线样本均值作为区分目标和海杂波的分形特征值。仿真试验结果表明，这两种特征参数都能用以有效区分目标和海杂波。

| Abstract: | A target detection method based on the long-range dependence characteristic of sea clutter is proposed. By using the semivariogram function, the long-range dependence feature curve of sea clutter versus time is obtained. According to the curve, we suggest the slope and sample mean value of semivariogram curve as parameters to describe the fractal characteristics of the target and sea clutter. The analysis tests show that, with the two parameters, the target could be effectively distinguished from the sea clutter background. |
