Bistatic scattering from vegetation canopy in millimeter waves

In this paper mm wavelength is used to understand the behavior of vegetation canopy. In remote sensing studies, which can be thought as a part of GIS, vegetation canopies and their frequency dependent behaviors are important. Although, the mm waves were used in this study, frequency takes place between optic and infrared bands were also used. On the other hand, larger penetration depth of millimeter waves relative to optics can supply extra information about soil contributions to vegetation canopies. The backscattering mechanism is related to physical parameters of canopies. These physical parameters are water contamination of single elements and soil covered by canopy. The results show that volumetric moisture content of soil contribution plays an important role in scattering phenomena of canopies.
