摘要
雷达遥感具有穿透力和全天候作业的优势,在环境保护领域中应用需求广泛。面对国家日益严峻的环保形势和最新发射的环境雷达卫星,急需系统介绍雷达遥感技术在环保领域中的应用。文章通过全面分析合成孔径雷达(SAR)在溢油、水华、土壤湿度、植被长势、生物量以及应急监测等环境保护中的应用,为已经发射的环境一号雷达卫星提供明确的应用目标,并为构建全天候、全天时的环境天地一体化监测体系提供重要的技术参考。
Radar remote sensing has the advantages of penetration and all-weather operation, which applies widely in environmental protection, and has great applied requirement. Facing the severe environment pressure, it is urgent and neces- sary for summary the application of radar remote sensing in environmental protection. The application of SAR （ Synthetic Ap- erture Radar） in the oil spill, algal bloom, soil moisture, vegetation growth, biomass and emergency incidents monitoring have been analyzed systematically, so as to provide the clear applied goals for the HJ-1 C radar satellite, and attempt to sup- ply important technique service for the construction of space-ground integrated monitoring system.
