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.
