Abstract

The method uses a radar equipment (RG) mounted on an overbridge (BR) to direct a steeply inclined beam (RS) on to each vehicle (FZ) entering the area of road (SB) covered by the radar antenna (ANT). The shape of the vehicle is recognisable from the different components of the radar echo associated with scattering from its edges and corners, and with specular reflection from smooth surfaces. Fine identification is based on continuous measurement of the Doppler frequency of the variation in slope of the tangent to the outline of the vehicle. Additionally, a speed of vehicle is measured as a basis for obtaining horizontal profile data, e.g. vehicle length.
