极化比模型比较和选择的研究

Study on comparison and choice of the polarization ratio models

极化比模型是使用HH极化SAR图像反演海面风场的关键问题。深入研究了现有的极化比模型,对其进行了比较分析。利用实测极化比,对各种极化比模型的性能,进行了统计评估。提出了不同入射角时、不同风速时极化比模型的最佳选择,其结论对实际应用具有指导意义。

Polarization ratio models are the key issue when HH polarization SAR images are used to retrieval sea surface wind field. Based on the deep research and comparison on the existing polarization ratio models, the performance of various polarization ratio models are statistically assessed. At last, the best choice of polarization ratio models are proposed under different incidence angles and different wind speeds, and it is useful for practical application.
