Development and Calibration of a Prototype Radar for Sea-Tide Level Measurement

We developed a prototype radar for sea-tide level measurement. The radar was evaluated in a laboratory room. It was confirmed that the radar could detect the change in the position of a target with a resolution of <;1 mm. We also evaluated the phase-detection performance of scattered waves in an anechoic chamber and confirmed that the phase profiles measured at vertically different antenna positions agree well with theoretical calculations.
