全球导航卫星反射信号遥感(Global Navigation Satellite System Reflectometry,GNSS-R)是近年来新兴的学科交叉研究领域,其通过接收导航卫星(如GPS、北斗)的海面/陆面反射信号来获取参数信息(如海面高度、土壤湿度等).GNSS-R的最终目标是实现大范围、全天时、高时间分辨率的星载观测,航空飞行试验是实现星载可行性论证的必要条件.本文报道中国2014年5月于河南郑州开展的GNSS-R航空飞行试验概况,并给出陆表参数——土壤湿度的估算方法和结果分析,为中国GNSS-R观测试验开展、自主载荷研制、陆面观测数据处理等提供参考.
The Global Navigation Satellite System Reflectometry (GNSS-R) is a new field of interdisciplinary research in recent years. It obtains the parameter information by receiving the sea / land reflection signals from navigation satellites (such as GPS and Beidou) Such as sea level, soil moisture, etc.) The ultimate goal of GNSS-R is to realize on-board observations in a wide range, all-day and high-resolution time-lapse, and aviation flight tests are necessary conditions for the feasibility study of on- GNSS-R aviation flight test conducted in Zhengzhou, Henan Province in May 2014, and gave an estimation method and result analysis of the land surface parameter-soil moisture. It was carried out for China’s GNSS-R observational experiment, autonomous load development, land surface observation Data processing, etc. provide a reference.
