Abstract

Satellite radar altimeters have demonstrated a wide range of scientific capabilities over oceans and ice, and have considerable potential over land and inland water /1/. However, the universal adoption of the single-beam, pulse-limited mode of operation limits the spatial and temporal sampling achievable, and makes the generation of surface elevation maps critically dependent on the accuracy of the satellite orbit reconstruction. Also, over topographic surfaces, the data can be difficult, sometimes impossible, to interpret. With the advent of the Columbus polar platform, previous limitations on the size and complexity of space instruments will not apply. We consider what types of swath altimeter might take advantage of this possibility and conclude that both multi-feed, large antenna instruments and an interferometric design could provide valuable advances. Ultimately, a scanning beam, phased array instrument could provide full global coverage with high spatial resolution. © 1987.
