新型遥感技术在地表参数反演中的应用现状和潜力

Application Status and Potential of New Remote Sensing Technology in Surface Parameter Inversion

地表参数在监测地球资源与环境信息时具有很高的价值。目前,新型遥感技术已经被广泛用来研究大尺度上地表参数的时空分布状况,其中极化合成孔径雷达可用于反演地表粗糙度及土壤水分;被动微波遥感已被广泛应用于积雪、植被等地表参数反演中;全球导航卫星系统反射遥感技术能用于反演海洋和陆地的几何与物理性质。随着遥感反演理论等的不断发展,新型遥感技术将在地球系统的研究及应用中承担更为重要的的角色。

Earth surface parameters are of great value in monitoring the information of earth resources and environment.At present,new remote sensing technologies have been widely used to study the spatial and temporal distribution of earth surface parameters on a large scale,among which Polarized SAR can be used to retrieve the surface roughness and soil moisture;Passive microwave remote sensing has been widely used to retrieve surface parameters such as snow cover and vegetation;GNSS-R technology can be used to retrieve the geometric and physical properties of oceans and land.With the continuous development of remote sensing inversion theory,new remote sensing technology will play a more important role in the research and application of the Earth system.
