The v[...]

M. Moran ; A. Vidal ; D. Troufleau ; AL Et | 1998A method is proposed to estimate both green leaf area index (GLAI) and soil moisture (h(v)), based on radar measurements at the Ku-band (14.85 GHz) and C-band (5.35 GHz) frequencies. The Ku-band backscatter at large incidence angles was found to[...]
