Microwave response of green vegetation

Abstract

The cavity perturbation technique has been used to measure the dielectric constant of vegetation, such as soyabean, grass, corn and green spruce at 9.5 GHz. The dielectric properties of these vegetations are highly dependent upon the moisture content. For freshly plucked specimen the dielectric constant was found to be maximum which decreased gradually as the specimen dried up. The role of these basic physical parameters in microwave scatterometer experiment has been discussed. Some parameters of remote sensing application have been estimated from these measurements and their practical role has been discussed © 1982 Indian Academy of Sciences.
