SAR图像变化检测传统方法综述

Overview on Traditional Methods of SAR Image Change Detection

合成孔径雷达(SAR)卫星具有全天候,全时间对地面情况监测的特点,在获得同一地点多时图像方面有着巨大优势。变化检测(change detection)是遥感领域中一个重要的应用手段,在洪水监测,建筑物变化监测,农作物生长情况,地震灾害灾情损失估计等方面有着广泛的应用。如今,合成孔径雷达中的变化检测方法逐渐变成未来遥感图像研究中的热点。在本文中,对几种合成孔径雷达的传统方法进行比较和分析。

Synthetic aperture radar(SAR) satellite has the characteristics of all-weather and all-time ground monitoring.It has great advantages in obtaining multi temporal images of the same place.Change detection is an important application measures in the field of remote sensing.It is widely used in flood monitoring,building change monitoring,crop growth,earthquake disaster loss estimation and so on.Nowadays,the change detection method in synthetic aperture radar has gradually become a hot spot in the research of remote sensing images in the future.In this paper,several traditional methods of synthetic aperture radar are compared and analyzed.
