摘要
该文通过建立不同尺度下的平均波动,分析了海杂波的自仿射性质,提出一种基于波动分析的海上小弱目标检测方案。根据波动曲线的线性特征,以q阶归一化波动曲线斜率作为区分目标和海杂波的分形特征值。对实测数据的试验结果表明,该文方法对不同环境、不同极化情况下获取的实测数据能够从海杂波背景下可靠地检测出目标。
Based on the fluctuation analysis, a novel approach for target detection in sea clutter is proposed. The self-affinity and scaling behaviors of sea clutter is analyzed by using the mean fluctuation. The q order normalized slope of fluctuation curve, as the characteristic parameter, is suggested to describe the fractal property of the target and sea clutter. The tests on the real data show that the target could be clearly distinguished from the sea clutter background with the proposed approach.
