Radar Technology for River Flow Monitoring: Assessment of the Current Status and Future Challenges

As an emerging non-contact method of flow monitoring, radar technology compensates for the shortcomings traditional methods in terms efficiency, timeliness, and difficulty monitoring high floods, can provide accurate measurement results, making it one most promising future. This paper describes detail workflow from data acquisition to calculation; compares analyzes current state-of-the-art signal sampling its limitations, Doppler spectrum estimation, processing inversion; points out challenges that these technologies may face future; provides corresponding solutions order improve real-time accuracy hydrometric as well promote development technology.
