Tyco Electronics Corp. unveils its High Resolution Radar (HRR) for the next generation of "Smart Bumpers."
Tyco says its system offers significant advantages over ultrasonic sensing systems, including greater range, higher resolution between objects and important styling advantages.
HRR works by transmitting a short pulse into a desired area. This energy is reflected off objects within 66 ft. (20.1 m) and returns. The travel time of the signal determines the range of the object.
The HRR system can "see through" plastic fascias commonly used on vehicles, eliminating the need for stylists to contend with unsightly external ultrasonic sensors.
