Abstract :
Remote sensing is actively used in observation of the nature. Synthetic aperture radar (SAR) systems are capable of obtaining physical based data under day/night and clear/cloudy sky situations. With sensitivity over the physical changes, they have importance in monitoring of agricultural areas. Paddy rice has been a widely used crop in the World, which requires wetland areas. In Turkey, it is mainly irrigated in Edirne and Samsun. With its importance in World´s agricultural economy, researches regarding the precision farming of rice increased significantly, which includes remote sensing methods. Here, the effect of phenological changes during growth of rice over dual-pol SAR (phase + amplitude) data are discussed. Fields that are located in Ipsala (Edirne) are chosen as test-site. Ground measurements are conducted during May-September 2013. SAR data that are used to explain the physical changes, are obtained in horizontal-horizontal and vertical-vertical polarization configurations from TerraSAR-X (TSX) and TanDEM-X (TDX) satellites in 2012 and 2013.
