La première configuration d'inversion est basée sur l'estimation de la rugosité du sol à très haute résolution spatiale "THSR" (échelle de la parcelle ou à plus petite échelle)
, En effet, après une forte pluie le sol est supposé être humide. En l'absence de pluie depuis quelques jours, le sol est supposé être sec ou légèrement humide. L'utilisation d'une connaissance a priori sur l'humidité du sol
, La deuxième configuration d'inversion concerne l'estimation en même temps de la rugosité du sol (Hrms) et de l'humidité du sol (mv). Les deux polarisations VV et VH
, THSR" utilisant VV seul, VH seul ou VV et VH ensemble) et en utilisant les deux modèles de rétrodiffusion radar (IEM_B et Baghdadi), les meilleurs résultats sont obtenus en utilisant la polarisation VV seule pour le modèle IEM_B et les polarisations VV et VH ensemble pour le modèle semi-empirique de Baghdadi. L'humidité du sol pourra être estimée avec un RMSE de l'ordre de 6 vol.% quand une information a priori sur l'humidité est utilisée dans les réseaux de neurones (construits à partir du modèle IEM_B ou du nouveau modèle semi-empirique). Le deuxième réseau de neurones utilise cette estimation de mv pour estimer la, En utilisant la première configuration d'inversion du signal radar (estimation de la rugosité du sol à très haute résolution spatiale
