水文站和船载测量的方法测量河流断面的流量受到船舶航行和河流水文条件的限制.本文以UHF雷达探测长江武汉段的试验数据为基础,构建表面流速与断面流速分布的关系模型,进而估算断面流量.把估算的结果与实测数据对比,验证了利用岸基UHF雷达测量河段流量的可行性. Hydrological station and shipborne method of measurement The flow of a river section is limited by the navigation of the ship and the hydrological conditions of the river.Based on the experimental data of the UHF radar detecting the Wuhan section of the Yangtze River, a model of the relationship between the surface velocity and the section velocity distribution is constructed, The cross-section flow rate is compared with the measured data to verify the feasibility of using the shore-based UHF radar to measure the river flow.
