Bistatic microwave remote sensing of kidney bean at 9.89 GHz

Abstract

Indigenously designed experimental studies have been carried out to study the microwave signatures of kidney bean which is a type of vegetable crop. An outdoor observation crop-bed was prepared in the vicinity of the Department of Electronics Engineering, Institute of Technology, Banaras Hindu University. For this study, a bistatic microwave scatterometer was employed to work in X-band of the frequency spectrum. Observations were carried out for the several growth stages of kidney bean. From the collected data, brightness temperature (TB) and the scattering coefficient (σo) were computed and their dependence on look angle were analyzed. The dependence of these parameters on look angle, polarization and moisture.
