Abstract :
In this paper we propose a new simple algorithm for data processing of GNSS reflectometry. At first step of data processing of interference patterns the algorithm allows to retrieve the modulus of the reflection coefficient and then retrieve soil moisture and surface roughness of the soil. This method allows to not take into account information about the antenna pattern and height of GNSS antenna, and also excludes the impact of geodesic relief roughness. The proposed methodology was used for the retrieval moisture and surface roughness of soil using data recorded GPS receiver on a vertical polarization.
