| 英文摘要 | In this paper we study the effect of shadowing functions to the bistatic scattering coefficients from random rough surfaces. The bistatic scattering strength is developed based upon a pair of the integral equation. Due to the use of tangential surface fields in the derivative of the scattering coefficients from the integral equations, the shadowing functions should be added to correct the scattering coefficients to meet the actual scattering situation. For correct prediction to the scattering characteristics we apply the suitable shadowing function to the bistatic scattering power from random rough surfaces. The comparisons of scattering coefficients with or without shadowing functions are shown to evaluate the effect of shadowing function in the scattering field from random very rough surfaces. To evaluate the function of shadowing function, we also compare the scattering coefficients with the measured data and find the good agreements in the scattering coefficients with shadowing functions. |
