Abstract
The intensity of sea surface scattered energy can be mapped with the use of Delay-Doppler Map (DDM) obtained by means of Global Navigation Satellite System-Reflection (GNSS-R) remote sensing technology. This chapter introduces the principle of GNSS-R and its application in oil spill detection. A geometrical model for GNSS-R double-base sea scattering data analysis exploring the specular reflection point and the mean square slope model was built. The GNSS-R DDM generation algorithm based on the Jacobian determinant method is developed. It is applied for the oil spill DDM simulated using X-band marine radar data. The relationship between the signal characteristics and the oil spill information in DDM is found, and the performance of oil spill detection at different wind speed values is analyzed.
