Abstract
This paper presents the simulation results of thermal emission from a corn canopy. The corn stalks are modeled using the quasi-periodic approach. The wave attenuation through the corn leaves modeled as elliptical disks is taken into account in the simulations. The computed brightness temperature that depends on the azimuthal look angle shows the attenuation effects due to the leaves in addition to the coherence effects due to the periodic structure of the stalks.
