Abstract

Radar backscatter measurements were performed from the German Forschungsplattform Nordsee (FPN) in the North Sea in order to determine the ocean wave-radar modulation transfer function (MTF), which relates the backscattered radar power to the long surface waves. The radar operated quasi-simultaneously at 1.0 GHz (L band), 5.3 GHz (C band), and 10.0 GHz (X band) at HH and VV polarization by using a single antenna. MTFs obtained at these radar frequencies and polarizations are compared. Our measurements of the dependence of the MTF on wind speed and long wave frequency are in agreement with earlier measurements. It is shown that the dependence of the coherence between the backscattered radar power and the long ocean wave height is a strongly decreasing function of radar frequency. -from Authors
