摘要
全球卫星导航系统(GNSS)发展至今已有半个多世纪,不仅可以为用户提供导航、定位和授时(PNT)服务,还可用于地球遥感,其应用超乎想象.本文基于GNSS反射信号(GNSS-R)的应用,系统介绍了GNSS-R的基本概念和信号特征,重点针对陆面遥感应用进行了综述,并就未来可能的发展方向做出分析,可为GNSS-R的应用提供一个重要的参考.
Global Navigation Satellite System(GNSS)has been developed for more than half a century,and it can not only provide users with navigation,positioning and timing services,but also be used for remote sensing of the Earth,and its applications are beyond imagination.Based on the application of GNSS-R,this paper systematically introduces the basic concepts and signal characteristics of GNSS-R,focuses on the land surface remote sensing applications,and analyzes the possible future development directions,which can provide an important reference for the application of GNSS-R.
