ABSTRACT
A new concept of general satellite to satellite reflection altimetry
(never before tested from an orbit) can be useful not only for oceanography
over a wide range of time and space scales (which is its original intention)
but also for geodesy (gravity field determination and evaluation).
The geographic distribution of return signals and related topics of
reflection altimetry (a current technology experiment from CHAMP)
are investigated. The greatest benefit for both oceanography and geodesy
would be achieved if the low altitude reflection receiver were in a near
polar prograde orbit. Number of reflections from the ocean surface
is several times higher than from the traditional altimetry (at comparable
conditions).
