Abstract : An analysis of the radar cross section data acquired from the NORDSEE tower during the MARSEN Experiment by the Naval Research Laboratory was made. A dependence on both wind speed and sea state was expected, based on observations and results obtained during the Gulf of Mexico Experiment. The range of variation of wind speed and wave slope during MARSEN were substantial. However, within a narrow range of wind speeds the range of variation of wave slopes was insufficient to demonstrate a radar cross section dependence on it. The results contained herein display appreciable randomness at each slope value; this tends to mask a likely dependence of radar cross section on slope. These results do not conflict with those obtained in the Gulf of Mexico, some of which are included for comparison, they are just too limited in range to add independent support.
