| 摘 要： | 利用全球导航卫星系统的反射信号GNSS-R(global navigation satellite system-reflection)对海洋进行观测,目前已经成为一种新型遥感手段。介绍了一种最新研制的GNSS-R系统,以及使用该系统在北京怀柔水库开展的GNSS-R岸基测高实验。实验的目的,是在理想的湖面条件下验证系统的性能和检验测高算法的精度。实验得出:该系统能够在天线各阵元组合情况下实现GPS-R(global position system-reflection)信号的接收和处理;在把反演结果平均到1h后,使用C/A码的测高精度可达分米数量级。 |

| Abstract: | Ocean observation with the reflected signals received from GNSS already has become a new type of remote sensing tool. The paper describes a newly developed GNSS-R system, and a shore-based altimetry experiment in Huairou Reservoir lake of Beijing using data received by the system. Objective of the experiment is to demonstrate performance of the system and estimate altimetry accuracy of retrieval method in the perfect lake conditions. Results of the experiment show that the system can receive and process GPS-reflected data using several combinations of antenna elements, and the accuracy of the one hour average retrieval result with C/A code is up to decimeter. |
| Keywords: | GNSS-R shore-based altimetry GPS C/A code |
