Abstract :
A neural network algorithm trained by a physical vegetation model is used to retrieve soil moisture of a wheat crop during the whole crop cycle. The retrieval algorithm uses multifrequency and multiangular microwave radiometric data as inputs. The procedure is tested by using extensive measurements carried out in 1993 at the INRA Avignon test site
