摘要
通过对GNSS(global navigation satellite system)反射信号软件接收机和硬件接收机进行对比分析,提出北斗反射信号软件接收机的结构及模块,包括接收直射和反射信号的天线、四通道射频前端、采样量化变换器和数据处理工作站。设计实现北斗导航卫星反射信号处理软件的实现方法及软件整体流程,给出捕获及跟踪两大主要模块的详细流程及处理方法。进行海面测高的岸基实验,通过与实际海面高度的对比验证了软件接收机系统的实用性。
After comparing and analyzing GNSS（global navigation satellite system）reflection signal software receivers with hardware receivers,both the architecture and components for BeiDou reflection signal software receiver were presented including direct signals and reflections antennas,two channel RF（radio frequency）front ends,high speed A/D converter and the workstation for data processing.The implementation method and signal processing process of BeiDou reflection signal software receiver were elaborated,and program flow chart and processing method of capture and tracking were presented.Coast based verification experiment for sea altimetry was performed.The usefulness of software was verified by comparing real results.
