AI Technical Summary
Existing radar flow measurement technology suffers from low flow measurement accuracy, inaccurate velocity field reconstruction, weak anti-interference capability, poor adaptability, and insufficient real-time performance in complex flow conditions and wide cross-sections, failing to meet the real-time monitoring needs of water conservancy project scheduling and flood control and disaster reduction.
A collaborative monitoring network is formed by deploying multiple radars. Combining the characteristics of water flow and an improved radial basis function interpolation algorithm, the cross-sectional velocity field is reconstructed. The flow rate is calculated by the hierarchical integration method, and dynamic calibration is performed to improve measurement accuracy and adaptability.
It enables accurate reconstruction of cross-sectional velocity fields and efficient, stable, and real-time monitoring of flow under complex flow conditions, significantly improving flow measurement accuracy and anti-interference capabilities, and meeting the precise requirements of hydrological monitoring.
