ultra wideband Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applicati ...

radar Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track ...

, used for sensing and measuring distances to objects in proximity to each other. Commercial applications include: *Vehicles: parking assistance, backup warnings, pre-collision detection and smart

cruise control Cruise control (also known as speed control, cruise command, autocruise, or tempomat) is a system that automatically controls the speed of an automobile. The system is a servomechanism that takes over the car's throttle to maintain a steady sp ...

(measures the distance to the vehicles in front of you and if they get too close, throttle is released and brakes are applied). *Appliances: studfinders and laser tape measures. *Security: home intrusion motion sensors and perimeter surveillance. *Search and rescue: micropower impulse radar can detect the beating of a human heart or respiration from long distances.
