MEASUREMENT OF OCEAN WAVE HEIGHTS WITH A SATELLITE RADAR ALTIMETER

The launch of Geos 3 on April 9, 1975, by the U. S. National Aeronautics and Space Administration (NASA), represented the first step toward the goal of ocean surface remote sensing from space. Geos 3 is the first unmanned satellite to carry a radar system for observations of the sea. In particular, it carries a microwave short-pulse altimeter capable of measuring rms ocean wave height along its nadir track. This paper presents some of the first wave height plots made from such a spacecraft radar. These wave height plots are shown vs. distance along the satellite track; they agree reasonably well with ocean wave hindcasts and laser profilometer measurements of wave height, the errors being consistent with system resolution and internal and tracking loop noise.
