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。
The research on the detection of wake of a surface ship using spaceborne synthetic aperture radar (SAR) images is of great significance in the field of the ocean. It is a difficult point to detect and pinpoint the wake feature of SAR images in oceanographic image. The detection method of ship wake in SAR image is studied. According to the development of wake detection of sea surface ship in SAR image in recent years, the wake type and imaging mechanism are summarized. Wake detection and the current domestic and international wake detection algorithm, through the comparative analysis of these methods to draw their advantages and disadvantages, and the future direction of the study.
