Automatic, Continuous River Stage Measurement with a Millimeter-Wave FM- CW Radar
River stage measurements at many locations are fundamental for the analysis of dynamic events on rivers, including ice breakup. But, these data are frequently unavailable. A high-resolution, broadband millimeter-wave (26.5 to 40 GHz) Frequency Modulated-Continuous Wave (FM-CW) radar, with real-time...
