摘要
Abstract
A ship wake detection method based on modified normalized Hough transform was proposed in this paper according to the fact that parts of ships and their wakes are nearly on a straight line in advanced synthetic aperture radar( ASAR)image. Experiments were made to verified the method. On the one hand,the peaks were modified in Hough transform field; on the other hand, the constraint conditions confirming initial and end points of ships were amended. The experimental results show that the method of wake detection in the ASAR image can more accurately detect ship wakes.关键词
