Description:
Models for scattering from a vegetation layer treated as a collection of discrete scatterers usually assume far field interaction among scatterers. In a real vegetation medium such as a deciduous forest it is not always true that each leaf is in the far field of the others. This paper examines the additional effect when scatterers are permitted to be in the Fresnel zone. It is found that this in general causes the backscattering coefficient to be higher and also to have a larger rate of increase with frequency than the case of purely far field interaction.
