  abstract = {{T}he characterisation of soil surface roughness is a key requirement for the correct analysis of radar backscattering behaviour. {I}t is noteworthy that an increase in the number of surface roughness parameters in a model also increases the difficulty with which data can be inverted for the purposes of estimating soil parameters. {I}n this paper, a new description of soil surface roughness is proposed for microwave applications. {T}his is based on an original roughness parameter, {Z}g, which combines the three most commonly used soil parameters: root mean surface height, correlation length, and correlation function shape, into just one parameter. {N}umerical modelling, based on the moment method and integral equations, is used to evaluate the relevance of this approach. {I}t is applied over a broad dataset of numerically generated surfaces characterised by a large range of surface roughness parameters. {A} strong correlation is observed between this new parameter and the radar backscattering simulations, for the {HH} and {VV} polarisations in the {C} and {X} bands. {I}t is proposed to validate this approach using data acquired in the {C} and {X} bands, at several agricultural sites in {F}rance. {I}t was found that the parameter {Z}g has a high potential for the analysis of surface roughness using radar measurements. {A}n empirical model is proposed for the simulation of backscattered radar signals over bare soil.},
