Abstract :
Extraction of vegetation water content and soil moisture from microwave observations requires development of a high fidelity scattering model. A number of factors associated with the vegetation canopy and with the underlying bare soil should be taken into account. In this paper, we propose an electromagnetic scattering model for a corn canopy which includes the coherent effect due to the corn structure and takes advantage of recently advanced scattering models for dielectric cylinder of finite length and for rough surface.
