Interferometric Doppler Radar and Method for Wave and Water Level Measurement

摘要

Devices, methods and systems for wave and water level measurement using a single DC (direct current)-coupled CW (continuous wave) Doppler radar for detecting water elevation changes in time when installed up to several meters from the water surface. The radar is wireless and can stream continuous data to a local PC (personal computer) or base station in range of its radio. The radar can sample up to 40 Hz and can run on batteries for continuous sampling. The radars can include multiple radar configurations of 1, 2 and 4 radar configurations. Applications for this radar can include the measurement of beach run-up, free surface elevation in tidal zones, and storm surge elevations near bridges and critical infrastructure during storm events.

主权项

1. A wireless radar sensor for measuring water surface level and characteristics in time comprising:
a CW (continuous wave) Doppler radar coupled with a transit antenna and a receive antenna to transit a continuous wave wireless signal to a moving target and wirelessly receive a reflected signal; a signal processing circuit to process the received reflected signal to generate a digital data corresponding to a water level measurement; a power source for supplying power to the DC (direct current) coupled radar; and a micro-controller coupled with a cellular antenna to wirelessly transmit the digital data to a base station to measure wave and water level to detect water elevation changes.
