Claims44
A wearable radar reflector, comprising:
- a retroreflector configured to reflect radiation having a frequency of about 1 to about 300 GHz;
- and
- a garment configured to be worn by a pedestrian, wherein the retroreflector is attached to the garment and configured to retroreflect an information signal from a vehicle.
A method of preventing collisions, comprising:
- receiving a radar signal having a frequency of about 1 to about 300 GHz at a pedestrian location from a radar source;
- and
- retroreflecting the radar signal toward the radar source, wherein the retroreflection indicates information to the radar source about a position of a pedestrian at the pedestrian location.
