The experimental results show that the proposed calibration technique makes it possible for a millimeter-wave radar to precisely detect deep sub-wavelength displacement motions with a root mean square error (RMSE) of < 3%. Both simulations and experiments are carried out for a 120 GHz interferometric radar to detect the subtle displacement motions as small as 1/312 wavelength. The working principle of the proposed technique is discussed in details. Trust the WAVE Storm Tracking Team to provide you with the latest weather conditions for WAVE. This paper proposes a novel calibration technique by leveraging the radar sensor's ego-motion to extract the calibration parameters that are necessary for accurate calibration. 2 Louisville kids star in nationally-touring musical. A weather radar is used to locate precipitation, calculate its motion, estimate its type.

However, for the small displacement motions of deep sub-wavelength, the I/Q trajectory is so short that it cannot provide sufficient information for accurate signal calibration, which leads to false phase demodulation i.e. The Forecast Radar map shows where area of precipitation are expected to be in the next 20-30 minutes.

The conventional signal calibration in a quadrature radar relies on the I/Q trajectory. Signal calibration is the precondition for accurate linear phase demodulation.
Owing to the short wavelength, the millimeter-wave interferometric radar is superior in detecting the subtle vibration motions.
