摘要
海面风速风向是海洋动力环境监测的重要气象要素。本文阐述了利用机载GPS遥感手段实现海面风场反演的系统组成;详细介绍了GPS信号散射机理,进行数据采集和风场反演的理论模型与技术方法,给出了延迟映射接收机的技术指标和飞行试验结果分析。
Wind speed and wind direction are important meteorological factors in ocean dynamic environment monitoring. This paper described the architecture of ocean wind-field retrieval （WFR） system. And the theoretic models and implementation aspects for scattering characteristics of GPS signals from ocean surface and the wind-field retrieval are discussed. The specifications of Delay Mapping Receiver （DMR） and flight test result are given and analyzed in this paper. Finally the application of GPS remote sensing in oceanography is introduced.
