【摘要】 2008-05-12四川省汶川县境内发生8.0级地震,紧接而来的降雨天气严重影响了地震灾害遥感监测的实施。合成孔径雷达以其穿透云雾的能力,备受人们关注,成为抗震救灾遥感信息保障的重要数据源。利用COS-MO、TerraSAR、RADARSAT等高分辨率SAR数据对5·12汶川地震灾害的监测表明,合成孔径雷达在重大自然灾害遥感监测中起着非常重要的作用,特别是在多云多雨环境下合成孔径雷达起到的作用更加明显。更多还原

【Abstract】 One heavy earthquake with MS8.0 occurred on May 12,2008 in Wenchuan County,Sichuan province.After the earthquake,the bed weather has made the optical satellite acquired data difficultly.Microwave can transmit through cloud and rain,so synthetic aperture radar images has widely used in Wenchuan earthquake hazard monitoring and assessment.Using high-resolution SAR images,such as COMOS,TerraSAR,RADARSAT,the building and roads which has been damaged by earthquake were monitored and the landslides,debris flow,landslide-blocked lake were recognized.The result shows that high-resolution SAR images are a very important data source in natural hazard monitoring and assessment,especially in the cloudy and rainy weather.更多还原
