The value of the back-scattering coefficient of soil is dependent on its dielectric constant. An attempt has been made to estimate the scattering coefficient for a slightly rough surface for soil in combination with diesel, using the Perturbation Model. A database of the estimated Cj band (5.3 GHz) scattering coefficients for soil in combination with diesel for both horizontal and vertical polarization and different look angles has been generated. The results show that as the diesel contamination increases, the scattering coefficient decreases in both horizontal and vertical polarization. For active microwave remote sensing the scattering coefficient data for soil in combination with diesel for different weight percentage content is useful for image analysis and its applications. By using this database it is possible to design an active microwave sensor for remote sensing detection of oil, which would be useful in the field of environmental science. The backscattering coefficient for three different look angles (45, 50 and 55) has been calculated, which is desirable for space borne remote sensing sensors.
