Abstract :
A FM-CW ground base C-band scatterometer is used to measure the bare soil surface. The measurement was conducted at different incident angles and for two soil moisture conditions. In-situ measurement is also arranged simultaneously in order to verify the retrieved moisture. During the moisture retrieval, the integration equation method (IEM) is used. The results show that the method could be used to build up the soil moisture database and could then be used for satellite data applications
