摘要

本文给出了玉米冠层热辐射的模拟结果。采用拟周期方法对玉米秸秆进行建模。在模拟过程中,考虑了玉米叶片的椭圆波衰减。计算的亮度温度取决于方位角,除了显示由于茎的周期性结构引起的相干效应外,还显示了由于叶片的衰减效应。

Investigation of coherence in L-band thermal emission from com canopies
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.
