| Abstract: | One-dimensional Gaussian rough surface is adopted to simulate the actual sandy loam surface. Theelectromagnetic scattering with tapered wave incidence is studied by using method of moments. Some of factorsrestricting electromagnetic scattering coefficients,such as the root mean square,the correlation length,the soil＇smoisture,the incident wave＇s frequency,are discussed by numerical calculating. At the same time,the specific lawsof its changes with the said factors are summed. |
