| 5. | Based on the theory of rain - induced rain - induced cross - polarization discrimination ( xpd ) , the two - order small argument approximation for rain - induced xpd is developed , and a new model for predicting rain - induced xpd is proposed based on this approximation . the comparisons of this new model with other models and experiments data show that some improvement has been obtained with this model , especially for different polarizations 基于雨致交叉极化理论,提出了雨致交叉极化的二阶小变量近似方法以及新的雨致交叉极化预测模式,与其它模式和实验数据比较表明,该模式更能反映波的极化特征,较其它模式有一定的改进。 |
| 6. | The main contributions of the dissertation are as following : ( 1 ) according to the theories of co - polarization and cross - polarization scattered characteristics , co - polarization and cross - polarization scattering characteristics of typical targets have been analyzed detailedly in this paper . a mechanism is described that rough surface tilted ( symmetrical distribution scene ) conduces to estimate terrain slope . so , we can estimate an elevation outline of symmetrical distribution scene without any experiential knowledge 本文的主要贡献可归纳为以下五点:山厂村拈人学博十论义2001 ( l ) 4十日标的共极化和交义极化敞射理论,详细分析了典型11杯的共极化和交义极化敞射特性,网明倾斜的均匀分布场景(粗糙表而)的共极化敞射特性4i利十提取地形方位向高度轮廓的机jrp 。 |
