Abstract :
GNSS-R techniques have been used to retrieve altimetric and sea state information in ocean scenarios. This paper provides theoretical and experimental results of using Global Navigation Satellite Signals reflected (GNSS-R) over bare soil and vegetation-covered soil to retrieve soil moisture using the measurement of the power of the interferent field (direct + scattered).
