The purpose of this document is to specify minimum performance requirements and methods of test for the stationary, automated, across-the-road radar devices used by law enforcement agencies to measure, display, and record images of vehicles moving at excessive speeds along the Nations roads and highways. This document applies to radar speed-measuring devices that transmit an unmodulated continuous wave (CW) microwave beam across the roadway, monitor the signals reflected from the moving vehicles crossing the microwave beam, process the Doppler shifts of the reflected signals for the vehicle speeds, and may automatically record images of those vehicles which exceed a preset speed.
