Abstract

A harmonic radar and set of passive transponders are used for detection and identification of vulnerable road users (VRU) in automotive applications. The radar system transmits a signal consisting of two distinct frequency components in the 76-81 GHz band. A small transponder is carried by the VRU. The antenna and the electric circuitry of the transponder are printed on flexible film and it can therefore be integrated in clothes. In the transponder the two frequency components are mixed together and a harmonic product, offset from all other reflections, is transmitted back to the radar. By synthesizing this harmonic frequency the radar system can unambiguously identify and localize VRU.
