摘要：

GNSS Reflectometry (GNSS-R) is a remote sensing tool for extracting Earth surface information. This work presents a preliminary result of a static measurement applying the software GPS receiver. The system configuration consists of both Right Hand Circularly Polarization (RHCP) and Left Hand Circularly Polarization (LHCP) antennas for receiving reflected signals. Raw sampled data were stored into two PCs for post processing in order to get Signal to Noise Ratio (SNR) for both polarizations. Power reflectivity behavior was theoretically analyzed and compared with obtained results. A trial dielectric constant retrieval of the meadow was attempted, and the results were coherent with the in-situ soil moisture state.
