<p>PROBLEM TO BE SOLVED: To provide a consecutive non-contact measuring method that uses a microwave transceiver to measure, from a position distant from water's edge on a slope structure embankment of a river, a water channel for industrial or agricultural use, a reservoir, a lake, a marsh, or the like, water surface behavior of a water surface level and a surface water flow rate in a measured water surface, without directly building a structure on the embankment.SOLUTION: In a consecutive non-contact measuring method, a microwave transceiver integrating a transmitter and a receiver is installed in a position horizontally distant from water's edge to transmit/receive a microwave to/from a measured water surface in a direction inclined at a depression angle of 45 to 80 degrees, the microwave transceiver uses an FM-CW signal system and a Doppler signal system, the single FM-CW signal system measures a water surface level, and the FM-CW signal system and the Doppler signal system used in combination measure both the water surface level and a surface water flow rate, by switching between one and the another of the systems at an ultrahigh speed, consecutively in a non-contact manner.</p> |
