The invention discloses a large-span double-track circulating radar flow measurement system which comprises double-track circulating radar online flow measurement equipment and fixed-point radar online monitoring equipment. Compared with the prior art, the system has the advantages that the system is all-weather, unattended, full-automatic and remote telemetering, can measure flow at night and in rainy days, can measure flow under the conditions of high water level and high flow speed in flood periods, and is suitable for extreme environments with high sand content, floating objects, sewage and the like; large-span river channel multi-frequency measurement can be supported, the section can be strained in an advancing mode, and section flow state full-coverage detection is achieved; probe attitude and wind power and wind direction dynamic coupling are provided, the measurement precision is high, and the speed is fast; remote automatic accurate monitoring can be achieved, and corresponding vertical lines are au
