Abstract
In September 1979, the radar scattering coefficient ( \sigma\deg ) was measured at platform Noordwijk in the North Sea 10 km off the Dutch coast. This was done in conjunction with similar measurements by Dutch and French investigators as part of Project MARSEN (Marine Remote Sensing). Our measurements were made with vertical and horizontal polarizations, in the frequency baud 9-17 GHz, at incidence angles 0\deg - 70\deg , with wind speeds from 2-22 m/s, and look directions upwind, downwind, and crosswind. This paper presents the scattering-coefficient variation with these radar and ocean parameters. In particular, the exponents for the windspeed response are compared with those from other investigators. Some of the exponents reported here are higher than reported previously, possibly because orthogonal regression was used rather than regression of \sigma\deg versus windspeed.
