Abstract
For a radar device arranged above a reflecting surface, a method is suggested for estimating the height of an object above the surface. This method does not require a refined angle resolution for the radar antenna and is based solely on the processing of signals. The invention makes use of the appearance of an interference pattern for the radiation field of the radar antenna, which normally is viewed as a disadvantage, by evaluating the intensity modulation of a signal received from an object moving in radial direction to the radar device within the surveillance range. Together with the measured distance to the object, this is used to estimate a value for the height of the object above the road surface.
