Microwave detectors (Dmgdeq)

Definition
Devices for transmitting electromagnetic signals and receiving echoes from objects of interest within their volume of coverage. Microwave sensors designed for traffic data collection in U.S. roadside applications are limited by FCC regulations to operating frequency intervals near 10.5, 24.0, and 34.0 GHz. FCC-approved frequencies for vehicle-mounted radars utilized in collision avoidance, obstacle detection, and automatic cruise control are 47.5 to 47.8 GHz and 76 to 77 GHz.
