Study and Implementation of Ocean Wind-field Remote Sensing Method Based on GPS Satellite Signal
【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。
【Abstract】 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.
