| 摘 要： | 海浪极化SAR成像模拟对海面散射的研究有重要的意义。该文根据海浪随机理论进行了粗糙海面建模,利用海面的双尺度模型构造了包含涌浪的随机粗糙海面;同时考虑了大、小尺度的海面的影响。基于该海面模型,利用Bragg散射模型和几何光学近似法模拟了不同风速情况下海浪的极化SAR图像,并对海浪参数及SAR参数对极化图像的影响做了分析,得出了一些有益于海浪信息提取的结论。

| Abstract: | Simulation of polarization synthetic aperture radar(SAR) imaging of sea wave has great significance on sea surface scattering.According to the theory of random ocean wave,rough ocean surface is modeled in this paper.Random rough ocean surface which contains swell is constructed using the two-scale-model.This treatment takes both the large scale and small scale surface into account.By using the Bragg scattering model and the geometry optical approximation method,polarization SAR images of the modeled ocean s... |
