Abstract : A radar altimeter with one meter accuracy has been proposed for a geodetic and oceanographic satellite to measure the mean level of the surface. It is reported by Pierson that an altimeter with such an accuracy could detect (a) intermediate and smaller scale geoid features, (b) local sea surface slopes due to strong ocean current, (c) tides storm surges and tsunamis, and (d) mean sea level. Existing techniques for measuring time delay in electronic circuits are more accurate than required in the proposed system, so the primary errors are those associated with the signal fading caused by scattering from extended targets such as the ocean's surface and by the biasing effects caused by the variations in sea state.
