The surface of Mars is characterized by a large variety of geological processes and provinces which are likely to be related to different subsurface structures. However, the subsurface of Mars is very little known. MOC images have recently shown several outcrops with layered deposits of 2-4 km thickness. The different characteristics of each layer suggest that the Martian upper crust has been sculptured by a wide range of geological processes. The MARSIS radar experiment which will fly on the Mars Express mission will show for the first time the characteristics of the subsurface of Mars. SHARAD on board Mars Reconnaissance Orbiter will performed a more detailed investigation of the subsurface. In order to provide a range of inputs for testing the resolution of the MARSIS and SHARAD radar instruments, we suggest models for a few areas of Mars with different geological settings. The selected areas are: 1. chaos areas where indications are strong for occurrences of ground ice and possibly gas hydrates, 2. canyons and adjacent areas where layering is visible on the walls, 3. sedimentary deposits of various thickness and lithology (lacustrine, fluvial), 4. volcanic areas and associated deposits, 5. glacial landforms and polar caps deposits. This stratigraphical analysis will help us to understand the capabilities of the radar instrument to detect geological features in the upper crust of Mars. The models and simulations are done with respect to differences in electric properties between different layers as well as differences of variation in layer thickness compared to terrestrial analogues studies. Further information about the shallow-water reservoir has been obtained by the Mars Odyssey and Mars Global Surveyor data.
