摘要
利用星载合成孔径雷达(SAR)图像进行海面船只尾迹检测的研究在海洋领域具有重要意义。SAR海洋图像中尾迹线性特征的检测和精确定位是个难点,研究了SAR图像中船只尾迹的检测方法,根据近年来SAR图像海面船只尾迹检测的发展,总结了尾迹类型及其成像机理,分析了影响尾迹检测的因素和目前国内外的尾迹检测算法,通过对这些方法的对比分析得出它们的优缺点,并对今后的研究方向进行了展望。
Researches of ship detection using Synthetic Aperture Radar (SAR) images have received consid erable attentions in the area of marine. The problem of the detection and accurate positioning of ship wake linear feature in the SAR ocean imagery is one of great difficulty. This paper discusses the detection of ship wakes, according to the study on ship wake detection technology in SAR imagery in recent years, this paper summarizes the kinds and imaging mechanism of ship wakes,the factors that would affect ship wake detec- tion and the all kinds of wake detection algorithms are analyzed, and obtains the merits and demerits of al- gorithms. The future direction of research and development is viewed.
