Abstract
We discuss simulator units for calibrating across-the-road Doppler traffic radars used in highway speed enforcement. Two units of essentially the same design were developed, one operating at K-Band (24 GHz) and the other at Ka-Band (35 GHz). The signal received from the radar is frequency modulated at rates that correspond to the expected Doppler shift for approaching and receding vehicles traveling at speeds of 25-200 km/h, and subsequently retransmitted back to the radar. The required calibration accuracy is 1.6 km/h at 90 km/h.Conference Dates
