Abstract |
Abstract – The Electromagnetic radiation that is emitted by the object carries specific properties about it. Emissivity is one of the frequently used passive remote sensing parameters for objects. In literature, remote sensing of vegetation includes different methods that are based on measurements with active and passive remote sensing. In this study, vegetation components are considered separately that leaves are modeled as dielectric disks and branches and trunks are modeled as cylinders for passive remote sensing for the first time in the literature. Emissivity and absorption cross section equations of geometrically facilitated vegetation are found out using two approximations. Emissivity for leaves is calculated using physical optics approximation on disk. In branches and trunks, infinite length approximation is applied on a cylinder. To check the accuracy of calculations, absorption cross section calculation results are compared with literature studies, and good agreement is found. The emissivity of human is simulated and the effects of each parameter are examined. Keywords - Emissivity, Modeling, Simulation, Vegetation. | |||||||||
