摘要
河流是人类重要的用水来源,同时也是地球水循环的重要组成部分.目前的河流监测方法大多采用水文站监测方式,但在恶劣环境下监测仪器易损坏,导致水文站测量数据的缺失.雷达技术具有全天时、全天候对地观测能力,不易受到环境干扰.本系统基于雷达高度计和SAR(Synthetic Aperture Radar)遥感技术,实现了河流宽度、水位及径流等参数的计算功能.本系统的推广应用能够为河流径流监测工作提供更好的技术支撑.
Rivers are an important source of water for human beings and an important part of the Earth’s water cycle.Most of the current river monitoring methods use hydrological station monitoring methods,but in harsh environments,monitoring instruments are vulnerable to damage,resulting in the lack of hydrological station measurement data.Radar technology has all-weather and all-weather ground observation capability,and is not susceptible to environmental interference.Based on radar altimeter and SAR(Synthetic Aperture Radar,SAR)remote sensing technology,the system realizes the calculation functions of river width,water level and runoff.The popularization and application of this system provide better protection for river runoff monitoring.
