IEEE 2450-2019 IEEE Standard for the Performance of Down-the-Road Radar Used in Traffic Speed Measurements

IEEE 2450-2019 Стандарт IEEE для исполнения погружного дорожного Radar Используется в скорости движения Измерения

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.
