  abstract = {{T}he objective of this paper is to present the contribution of a new dielectric constant characterisation for the modelling of radar backscattering behaviour. {O}ur analysis is based on a large number of radar measurements acquired during different experimental campaigns ({O}rgeval' 94, {P}ays de {C}aux' 98, 99). {W}e propose a dielectric constant model, based on the combination of contributions from both soil and air fractions. {T}his modelling clearly reveals the joint influence of the air and soil phases, in backscattering measurements over rough surfaces with large clods. {A} relationship is established between the soil fraction and soil roughness, using the {I}ntegral {E}quation {M}odel ({IEM}), fitted to real radar data. {F}inally, the influence of the air fraction on the linear relationship between moisture and the backscattered radar signal is discussed.},
