摘要
利用导航卫星反射信号(GNSS-R)进行海风海浪探测为海洋气象提供了一种新的观测手段,数据分析及有效性检定是确定系统探测能力的重要过程.在描述北斗GEO卫星进行海风探测机理的基础上,利用北斗反射信号的相关时间进行了海风的反演.同时针对国家北斗应用项目"基于北斗导航卫星的大气海洋和空间监测预警应用示范工程"在山东进行试验和试运行期间产生的风速观测数据进行分析,并通过与标准数据的对比,确定了该方法的有效性.
The ocean wind and wave sensing utilizing reflected signal from Global Navigation Satellite System（ GNSS） provides a novel detection approach for marine meteorological observation,while the data analysis and validity verification are important to evaluate the performance of this technology. This paper introduces the sea wind detection mechanism using Beidou GEO satellites,and retrieves the sea wind based on the correlation time of the reflected signals of GEO satellite. The data collected by Beidou ocean remote sensing station of Shandong,which was set up for the demonstration of the Beidou application in oceanic,atmospheric and space monitoring and early warning program,are analyzed and compared with standard data,and the results prove the validity of the proposed method and the system.
