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.

Interferometric doppler radar and method for wave and water level measurement

A system, method and apparatus tracks targets (e.g., tumors) during treatment (e.g., radiation therapy) using a radar motion sensor by generating a microwave signal, radiating the microwave signal to a subject, and receiving a modulated microwave signal from the subject. The modulated microwave signal is processed to provide a subject motion information using a sensor having an arctangent-demodulation microwave interferometry mode. A location of a target on or within the subject is determined based on the subject motion information and a three-dimensional model for the subject and the target. One or more control signals are generated based on the location of the target, and the treatment device is controlled using the one or more control signals to treat the target on or within the subject.
