MOCEM is a compact SAR image generator that can produce high resolution SAR images from CAD models (VRML, 3DS …) taking into account basic material descriptions. As an innovative approach, this software uses: - an original EM formulation based on the object geometry analysis to build SAR images in a very short computation time. These formulations have been developed by skillful SAR and RCS experts; - an original geometrical algorithm which handles the various facets visibility, including the multiple inner reflections and the interaction with the object surroundings (i.e. ground). SAR images are typically produced in a matter of minutes, using a 2D SAR radar transfer function that takes into account the main parameters of SAR image quality (resolution, Nesigmadeg, tapering). Many studies suffer from the lack of SAR images or control on SAR image content. This tool will interest scientists and labs, working on SAR image features extraction and SAR image analysis. A dedicated version called MOCEM LT has been developed for educational purposes. It offers an attractive way to explain capabilities and limits of SAR images to the scientific community which is more familiar with optical and IR images than radar.
