Abstract

The radar backscattering coefficients of soil surfaces with various roughness conditions are computed at first in this paper. The roughness parameters for various surface-profile lengths are also obtained. Then, the relationship between the radar backscattering coefficients and the profile length is studied. It was shown that the effect of the profile length is negligible on the backscattering coefficient, even though the roughness parameters vary a lot with the length of the surface profile.

본 논문에서는 토양 표면의 레이더 후방 산란 계수와 표면 거칠기의 관계를 계산해 보고, 측정 길이에 따른 표면 거칠기 변화를 알아본 후에, 측정 길이에 따른 표면 거칠기와 레이더 후방 산란 계수의 관계를 보여준다. 이 연구 결과에 따르면, 측정 길이가 짧아져서 표면 거칠기 값의 변화가 심하다하더라도 계산된 레이더 후방 산란 계수에는 적은 영향밖에 주지 않는다는 것을 보여준다.
