This paper deals with the simulation of very high spatial resolution images in the thermal infrared range, from 3 to 14 ƒm. It focuses on the conceptual architecture of a simulator of 3-D landscapes; its specifications are described and discussed. A new methodology is proposed for the simulation to best reproduce the properties of the infrared imagery. Particularly, this methodology enables a very accurate simulation of the signal coming from each object constituting the landscape. The

Their changes in time, and the recent past of the temperature and the humidity for each object, are taken into account. To reproduce these physical phenomena, the computation is performed on elements, which are defined as homogeneous entities with respect to the physical processes. This concept of element leads to a new methodology in design and realization of simulators. It permits to reproduce efficiently the behavior of the landscape in this spectral range at very high spatial resolution. Keywords: Infrared, simulator design, 3-D scene, very high spatial resolution, object interactions. * thierry.poglio@space.alcatel.fr; phone +33 (0)4 92 92 64 24; fax +33 (0)4 92 92 76 60; ; phone +33 (0)4 93 95 74 49; fax +33 (0)4 93 95 75 35;
