摘要:

我们报告的沿海实验,研究GPS L1反射。该活动在巴塞罗那港断路器上进行,致力于开发海况检索算法。为此目的建立的一个实验系统收集和处理GPS数据,以自动生成干涉复场的时间序列。离线分析ICF,并与一个简单的开发模型进行比较,该模型将ICF相干时间与有效波高(SWH)和平均波周期(MWP)的比值联系起来。使用该模型的分析表明,ICF相干时间和附近的海洋浮标数据之间的一致性良好。基于这一结果,初步结论得出的潜力沿海GNSS-R的海况监测使用半经验建模相关GNSS-R ICF相干时间SWH。

英文摘要:

We report on a coastal experiment to study GPS L1 reflections. The campaign was carried out at the Barcelona Port breaker and dedicated to the development of sea-state retrieval algorithms. An experimental system built for this purpose collected and processed GPS data to automatically generate a times series of the interferometric complex field (ICF). The ICF was analyzed off line and compared to a simple developed model that relates ICF coherence time to the ratio of significant wave height (SWH) and mean wave period (MWP). The analysis using this model showed good consistency between the ICF coherence time and nearby oceanographic buoy data. Based on this result, preliminary conclusions are drawn on the potential of coastal GNSS-R for sea state monitoring using semi-empirical modeling to relate GNSS-R ICF coherence time to SWH.
