内波海面海浪等效谱与SAR内波图像模型的关系

Relation Between Ocean Wave Equivalent Spectrum and SAR Image Model

内波海面的电磁计算模型一般把流体力学-电磁波模型简单处理并与SAR图像模式相结合。根据 电磁散射模型的计算要求,提出了一个等效的海浪谱模式,并用在电磁散射的计算,最后,用SIR-C/X-SAR在 中国南海海面的内波表面图像进行了对比,对L-和X-波段具有很好的计算结果。

The backscattering coefficients calculation is carried out with variable ocean wave spectrum and SAR image models. The results are not comparable with others because of variable spectrum. The present paper gives an equivalent spectrum to calculate the backscattering coefficients calculation of surface of internal wave. Finally, the calculation results are comparable with the SIR-C/X-SAR images of internal wave of South-China Sea.
