Abstract

When there exists overturning wave crest on the sea surface, the sophisticated coupling effect between the overturning wave crest and sea surface may give rise to sea spikes. As sea spikes will cause the increase of radar false probability, the investigation of electromagnetic (EM) scattering characteristics of threedimensional (3-D) local sea surface with time-varying overturning wave crest is meaningful for the remote sensing. In this paper, the influence of wind speed and time factor is taken into consideration when constructing the overturning wave crest, which is ignored in the traditional Longtank model. In addition, the Integral Equation Method (IEM) is adopted to calculate the EM scattering from a 3-D local sea surface with time-varying overturning wave crest for different incident angles and wind speeds. The simulation results are meaningful for analyzing the physical mechanism of sea spikes.
