Investigation of electromagnetic scattering interaction between the buried target and the rough surface in different types of soil
不同土壤类型的粗糙地面与其下方埋藏目标复合电磁散射研究

The problem of the composite electromagnetic scattering from 2-D buried target at the 1-D randomly rough surface with lossy media,which is different in different types of soil, is solved by the method of moments,while the tapered incident wave is chosen to reduce the truncation error.The relative dielectric constant of the soil could be calculated according to the frequency of the incident wave,the soil components,the soil moisture and soil temperature based on a cartain model.The Monte-Carlo procedure is employed to calculate the bistatic scattering cross section,which is dependent on the soil components,the soil moisture,the frequency of the incident wave,as well as the rms height of the randomly rough surface in details.The numerical results provide a guide in the application of ground penetrating radar in military,civil,as well as industrial fields.
