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. It may be applied successfully for oil spills detection. This paper builds a geometrical model for ship-borne GNSS-R double-base sea scattering data analysis exploring the ship-borne specular reflection point and the mean surface slope (MSS) model. The GNSS-R DDM generation algorithm based on the Jacobian determinant method is developed. It is applied for the oil spill DDM simulation using X-band marine radar data of the oil spill accident occurred in Dalian on July 21, 2010. 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.
