Response of microwave scattering from crop(wheat)and crop covered soil moisture for remote sensing

摘要

The present study investigates the potential use of active microwave observations at 9.5 GHz frequency of X-band to monitor soil moisture and vegetation leaf area index(LAI)over a wheat cover form remote sensing. Using an X-band (9.5GHz)scatterometer, measurements have been made out for different growth stage of crop(wheat). The leaf area index (LAI)is an important parameter for understanding the crop characteristics. Here an attempt has been made to highlight the effects of crop(wheat)LAI and crop covered soil moisture(m_g)on microwave scattering.
