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.
