Bistatic microwave remote sensing of kidney bean at 9.89 GHz

Indigenously designed experimental studies have been carried out to study the microwave signatures of kidney beans, 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 beans. From the collected data, the brightness temperature (T_B) and the scattering coefficient (σ^o) were computed and their dependence on the look angle, polarization and moisture were analysed
