Abstract
Two semi-empirical models, simulating the backscattering coefficient from d ifferent crops, were tested on the same wheat canopy. The physics of the se mi-empirical models and the limitations of these models when scattering eff ects are discussed. The results show that both models can be included in a generalized formulation adapted to a large range of measurement conditions. This conclusion confirms that the radar configuration (waveband, polarizat ion, incidence angle) plays a role similar to that of the canopy structure in the control of the radar backscattering coefficient.
