Studies of backscattering on isolated specimens began at the
90s, including the effects of wind speed on X-band radar echoes
, and introducing the backscattering function of a vegetation
specimen as an isotropic distribution in angular terms . Different
studies on the effect of the leaves detected that denser foliage
and larger leaves lead to stronger scattering [8,9]. A large measurement
campaign around different vegetation species, at various frequencies,
and a proposal of model to predict attenuation are the
goal of Specific research around isolated trees at millimetre
