The scope of this standard is limited to radar speed-measuring devices used by law enforcement agencies for enforcing vehicle speed regulations, where these radar devices are operated in a "down-the-road" (DTR) fashion, meaning that the radar is aimed in a direction nominally parallel to direction of travel on the roadway and toward traffic. These DTR radar units transmit modulated or unmodulated continuous-wave (CW) microwave energy, receive the signal reflected from moving vehicles within the microwave beam, process the Doppler shift of the reflected signal to measure and display the speed of the vehicle that is being tracked, and if applicable, the speed of the patrol vehicle. This standard does not apply to unmanned radar speed-measuring devices, automated speed enforcement, or DTR radar range measurements. The purpose of this standard is to specify the baseline performance requirements and associated test procedures for radar speed-measuring devices used by law enforcement agencies for enforcing vehicle speed regulations. This standard does not define a product conformity program. New IEEE Standard - Active. Baseline performance requirements and associated test procedures for down-the-road (DTR) traffic radar speed-measuring devices are established in this standard. Modulated or unmodulated continuous-wave (CW) microwave energy is transmitted, the signal reflected from moving vehicles within the microwave beam is received, the Doppler shift of the reflected signal to measure and display the speed of the vehicle that is being tracked, and if applicable, the speed of the patrol vehicle, is processed by these DTR radar devices. Unmanned radar speed-measuring devices, automated speed enforcement, or DTR radar range measurements are not covered in this standard.
