This paper investigates the possibility of monitoring of the ground surface condition under the rice crop canopy based on a numerical scattering model preliminarily. The model used here is the Michigan microwave canopy model. In order to apply to the rice paddy field, a developed module for it is added. It is found that the ground surface condition under the canopy can be detected at the incident angle of less than or equal to 25 degree at C-band and at the incident angle between 10 and 50 degree at L-band. It is possible to monitor the ground surface condition under the canopy, if the sensor configuration is designed for its purpose. However most systems mounted on the operational SAR satellites do not suit with the purpose.
