Abstract :
This paper constructs a randomly rough surface via the Fourier series of the surface height function and analyzes the statistical characteristics of the Fourier coefficients. Using this expression of spectrum domain, a different type of the Kirchhoff model named the spectrum domain Kirchhoff model (SDKM) is obtained to calculate the scattering coefficient. Comparison between SDKM and the original Kirchhoff model shows that the SDKM has obvious advantages.
