报载,去年我国在抗洪抢险斗争中,遥感技术发挥了重要作用,功不可没。去年7月下旬,装载着特殊雷达的飞机,多次在洞庭湖洪涝地区上空作了飞行遥感监测,雷达波穿透浓厚的云层,侦察监测了27000平方公里内的大范围水情信息,迅速、准确地为政府部门提供了第一手灾情报告。与此同时,中国科学院北京遥感人造卫星地面站,利用微波遥感人造卫星对长江中、下游广大地区的水情,进行了全天候(不受天气条件和昼夜时间差的影响)的动态地面监测,获得了多次遥感成像,并将这些准确、高分辨率、实时性的遥感图像迅速送达中央领导和国务院有关部门领导的手里,为领导部门指挥抗洪抢险斗争,提供了宏观的科学决策依据。 遥感技术,是利用装载在飞机或者是航天器(如人造卫星)上的遥感系统,
According to the newspaper, remote sensing technology played an important role in the flood fighting and emergency rescue in our country last year and contributed to it. In late July last year, aircraft carrying special radars repeatedly made flight remote sensing monitoring over floodwater areas in Dongting Lake. The radar waves penetrated thick clouds and scout monitored a wide range of hydrological information within 27,000 square kilometers. Rapid, Accurate government departments provided the first hand disaster report. At the same time, the Chinese Academy of Sciences Beijing remote sensing artificial satellite ground station, the use of microwave remote sensing artificial satellite on the Yangtze River in the vast area of hydrological conditions, all-weather (from weather conditions and the impact of time difference between day and night) dynamic ground monitoring obtained Many times remote sensing imaging, and these accurate, high-resolution, real-time remote sensing images quickly served on the hands of the leaders of the Central Government and the relevant departments of the State Council, providing the macro scientific basis for decision-making for leading the department to direct the flood fighting and rescue operations. Remote sensing technology is the use of remote sensing systems loaded on aircraft or spacecraft (such as satellites)
