| Popis: | 95 In this study, a novel scheme of river hydrological information measurement produced by reflected global position system (GPS) signals in combination with digital terrain elevation data (DTED) level 2 is presented here. The reflected GPS signals from river water level are obtained by ameliorated antenna. And the signals are computed into reflected trajectory points and water level altitude variations via a new application of GPS signal process. Afterwards the parameter reckoning water level altitude variation is amended on accuracy by contrast between DTED and results of processed signals Besides, the Doppler value is analyzed to estimate the surface velocity of stream flow by velocity transformation matrix. And the integration can be applied to compute river water-level and velocity of stream-flow as monitoring fluvial discharge, especially during freshet. |
