GPS卫星信号测量波浪技术研究

Research on GPS Satellite Signal Wave Measurement Technology

随着我国沿海地区经济越来越发达,人口越来越密集,在历年的海洋灾害中,海浪造成的人员死亡失踪以及经济财产损失都高居第2位,增强沿海地区波浪的精细化监测和精细化预报具有十分重要的意义。波浪浮标是最常用的波浪观测设备,本文给出了一种利用GPS卫星导航定位系统信号测量海浪的方法,它与传统上的利用重力加速度原理测量海浪的方法不同。本文分析了GPS卫星导航定位信号测量海浪的技术方案,并通过实验室试验和海上现场比测试验,进一步验证了技术方案的可行性,为GPS卫星测波浮标的下一步大范围应用提供了科学的技术资料支撑。

With the development of coastal economy and the increasingly dense population in China, the casualties and economic losses caused by wave disasters are the second highest in the marine disasters over the years. Therefore, it is very important to strengthen the fine observation and forecast of the coastal waves. Wave buoy is the most commonly used wave observation equipment. This paper presents a wave measurement technology using GPS(Global Positioning System) satellite signal, which is different from the traditional wave measurement principle using gravity acceleration. In this paper, the technical scheme of wave measurement with GPS satellite signal is analyzed in detail, and the feasibility of the technical scheme is further verified through laboratory test and field sea comparison test, which provides scientific technical data support for the further promotion and application of GPS satellite wave measurement buoy.
