| 中文摘要 | GNSS反射信号遥感技术(GNSS Reflectometry,GNSS-R)是外辐射源雷达遥感领域一项蓬勃发展的新兴遥感技术。该文从极化基础理论入手,对GNSS-R遥感多极化问题进行较全面的讨论,分别完成圆极化(左旋、右旋)和线极化(垂直、水平)接收方式下地表反射率与介电常数隐函数关系式的推导,并通过地基GNSS-R土壤湿度试验数据对公式合理性进行验证。该文的研究结论能够为GNSS-R仿真分析、观测试验设计、建模方法研究、数据处理与校正等提供参考。; GNSS Reflectometry(GNSS-R) is a currently developed remote sensing technology which belongs to the passive radar domain. This paper aims to deal with some issues on multi-polarization of GNSS-R technology. Four different polarization patterns of the received GNSS-R signal are discussed, including rl, rr, rv, rh. For each polarization, formulas for calculating the surface reflectivity(■) using dielectric constant(ε) and satellite elevation angle(θ) are derivated. The rationality of these formulas is validated using data from a ground-based GNSS-R soil moisture experiment. The results of this research can provide references for further GNSS-R research, including simulation, experiment design, model development and data processing. |
