Abstract :
As the resolution of new earth observation sensors increases, a precise modeling of the signal is necessary for the urban medium. For very high spatial resolution, 3D structure and directional effects must be taken into account. This paper aims to estimate the contribution of the facades and the directional properties in the simulation of at sensor signals. Two opposite urban scenes illustrate this study.
