Study on differential scattering field characteristics between soil surface and semi-buried target

In this paper, exponential distributed rough surface and Monte Carlo method are used to simulate the soil surface. Wang and Schmugge's four-component model is used to represent the dielectric properties of the soil. Based on the differential scattering field theory, the finite difference time domain method is used to study the composite electromagnetic scattering characteristics of the soil surface and semi-buried targets, and the frequency response curve of the differential radar scattering coefficient is obtained.
