Aptiv Technologies Limited. The method make use of a Doppler scattering phenomenon where a stationary object takes on different Doppler value due to the changing radial speed as the host-vehicle makes it way toward and eventually past the stationary object, where the radial speed is dependent on the speed of the host-vehicle and the angle to the object.
As long as the host-vehicle has a fixed trajectory (driving at a constant speed on a relative straight roadway) a stationary object such as a light pole, or speed limit sign can be tracked and the data can be stored and later used for calibration.At certain intervals determined at the time of the design, the radar goes into an on-line calibration mode. degrade) over time and/or due to changes in operating environment. 1 a two different instance in time in accordance with one embodiment; andFIG.

Also, this initial calibration does not compensate for changes of response due to aging or changes in environmental conditions, which can and often do lead to deterioration in system performance.
