| Abstract: |
| The influence of choosing ocean wave spectrum on Bragg resonance scat
tering modeling is a key problem of ocean surface electromagnetic wave scatterin
g modeling. This paper studies thoroughly about related problems.It int
roduces the concept of ocean wave spectrum, then chooses RA(Romeiser-Alpers) sp
ectrum to perform Bragg resonance scattering modeling, finally chooses another represe
ntative PM(Pierson-Moskowitz) spectrum to perform Bragg resonance scattering mode
ling.By simulation experiment two ocean wave spectrums and their effect of application in Bragg resonance scattering modeling are compared and analyzed.Conclusions drawn in this paper have guide meaning for choosing ocean wave spectrum reasonably. |
