Abstract

The GNSS signal which is reflected by the surface of the object carries the physical characteristic information of reflecting surface. Global navigation satellite system reflection (GNSS-R) is an emerging area of GNSS applications in the field of microwave remote sensing using multipath reflected signals. Meanwhile, using GNSS-R technology based on signalto-noise ratio (SNR) of interference signal to investigate environmental changes around the station has become a new research subject. Soil moisture estimation is one of the many potential applications of the GNSS-R technique. This paper presents our investigation of the characteristics of the GNSS interference signal. Through the experiments under the tree, interference signal before and after rainfall were analyzed and compared. It is found that interference signal frequency have changed significantly after rainfalls occurred. The experimental results show that: GNSS-R can be used to estimate the soil moisture by analyzing the frequency change.
