| 摘 要： | 提出了一种新的GNSS-R信号接收处理系统（GNSS-Rreceiver system,GRrSv.2）的结构及信号处理方法。该系统可同时针对直射和反射的GNSS信号协同处理,并输出可配置延迟和多普勒的二维相关值矩阵。为了验证系统的性能,进行了针对海洋和陆地遥感的机载和岸基验证实验,并给出了初步的实验结果。

| Abstract: | Earth-Reflected GNSS(Global Navigation Satellite Systems) signals have become an attractive tool for remote sensing.This brings out the need of signal receiver systems to process this kind of signals.This paper describes the architecture and signal processing issues of a new GNSS-R receiver system(GRrSv.2) that features enhanced capabilities for remote sensing based on reflected Global Positioning System(GPS) signals.The GRrSv.2 can process both GPS L1-C/A direct signals and reflections.Aircraft and land ba... |
