摘要
利用SAR图像进行舰船目标检测是近年来海洋监测一大研究热点,受到各国的高度重视,目前SAR已成为当今舰船检测、监视和定位的最有效手段之一。本文首先回顾了SAR图像舰船目标检测领域近20年的重要研究成果,而后对目前常用检测算法在原理和检测性能方面进行了分析比较,指出各算法的优势与问题,最后对该技术领域的发展趋势做出展望。
In recent years,ship detection using synthetic aperture radar （SAR） images is a hot-spot of the research on marine monitoring,has become one of the most effective means.The current SAR ship detection,surveillance,and targeting.This paper reviewed the field of SAR ship detection images nearly 20 years of important research results,and then detection algorithm used in the current theory and detection performance were analyzed and compared,pointing out the advantages and problems of each method,the the development trend of this technical areas was viewed in the end.
