The altimeter and sounding radar, one of the planned instruments on board the spacecraft in the Comet Nucleus Sampling Return (CNSR) mission, is addressed. This mission involves the study and design of a complete spacecraft system capable of landing on the comet nucleus and performing subsurface analysis. The requirements are recalled and the performance of a conventional beam-limited and pulse-limited radar altimeter are considered. In order to improve the horizontal resolution the synthetic aperture approach is proposed to be integrated to the radar altimeter.
