The coastal zone is important for human activity,which has the natural resources and frequent changes.Synthetic aperture radar (SAR) has the whole time,whole weather and high resolution advantage and has become the most important method for coastal zone monitoring.The SAR imaging coastal zone is discussed,SAR image interpretation signs of coastal zone features and SAR image processing methods.Also,several SAR image applications has been shown for coastal zone,including the coastal geology detection,coastal classification,development,utilization and the change of coastal zone monitoring.%海岸带自然资源丰富、变动频繁,是人类活动的重要区域.合成孔径雷达(SAR)以其全天时、全天候和高分辨率等特征,成为海岸带探测和动态监测的重要遥感器.论述了SAR探测地物的原理、海岸带地物的SAR图像解译标志和SAR图像处理方法.在此基础上,重点探讨了SAR图像在海岸带地质地貌探测、海岸分类、海岸带土地开发利用探测和海岸带动态变迁的监测等几方面的应用.
