Systems and methods for monitoring river flow parameters using a VHF/UHF radar station |
摘要 |
Systems and methods are described for monitoring the surface flow velocity and volume discharge of rivers and channels using a VHF/UHF radar located in operative relationship with a riverbank. This frequency region allows precise estimation and removal of the Bragg wave velocity; it also is matched to the short wind-wave roughness periods existing on river surfaces so that operation is possible nearly all the time. Methods of bearing determination are also disclosed. Up/downriver surface velocity profiles vs. distance across the river may be constructed from maps of the radial velocity component from a single radar at thousands of points within the radar's coverage. Methods to compensate for Doppler aliasing under high flow conditions are also shown.
