| Abstract: | 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. |
