Interaction of the Radar Waves with the Capillary Waves on the Ocean.

摘要

Measurements of the radar cross-section of the sea were made from the Noordwijk platform off the Dutch coast during September-November 1979 as part of Project MARSEN using an FM microwave spectrometer over the 8-18 GHz frequency range. A set of techniques for studying the modulation of the capillary waves on the ocean surface was developed for use in analyzing the entire observation set and is presented here as applied to a single set of observations. Thus, the results given here are only of limited oceanographic significance, but illustrate the types of analysis to be performed when these techniques are applied to more data. Measured scattering coefficient based on instantaneous radar footprint was cross-correlated with wave height and slope for measurements at the Noordwijk tower on 21 September 1979.
