This paper briefly overviews the status of the research in the development of new altimeter systems presently carried out in Alenia Spazio S.p.A. in the frame of internal research activities and ESA feasibility study contracts. In particular, the concepts of synthetic aperture and interferometric altimetry or global ice/land topography are reviewed in this paper. These system designs are extremely promising, since they can overcome the limitations of the classic nadir-looking pulse limited systems. Conventional system in fact, in spite of the extremely high range accuracy achievable over oceans, are unable to provide topographic details over ice or land due to their coarse horizontal resolution, several hundreds od meters against the 100-300 m required in ice/land topography applications.
