摘　　要：海浪谱的选择对Bragg共振散射建模的影响是海面电磁波散射建模的关键问题。首先简介了海浪谱的概念,然后选择RA(Romeiser-Alpers)谱进行了Bragg共振散射建模,最后选择另一种具有代表性的PM(Pierson-Moskowitz)谱进行了Bragg共振散射建模,并通过仿真实验对两种海浪谱及其用于Bragg共振散射建模的效果进行了比较分析。获得的结论对合理地选择海浪谱具有指导意义。The influence of choosing ocean wave spectrum on Bragg resonance scattering modeling is a key prob- lem of ocean surface electromagnetic wave scattering modeling. This paper studies thoroughly about related prob- lems. It introduces the concept of ocean wave spectrum, then chooses RA（Romeiser-Alpers） spectrum to perform Bragg resonance scattering modeling, finally chooses another representative PM（Pierson-Moskowitz） perform Bragg resonance scattering modeling. By simulation experiment two ocean wave spectrums and of application in Bragg resonance scattering modeling are compared and analyzed. Conclusions drawn per have guide meaning for choosing ocean wave spectrum reasonably. spectrum to their effect in this pa-
