Relationship between proŽ le length and roughness variables for natural surfaces

Abstract

Surface roughness variables such as the rms height and the correlation length are commonly used as inputs for electromagnetic models to predict the backscattering coe cient. The objective of this study is to investigate the in uence of the roughness proŽ le length on the estimation of roughness variables. Surface proŽ les of 25m long obtained by a laser proŽ ler have been examined. A clear dependence of exponential type was observed between the roughness variables and the proŽ le length.
