Frequency modulated continuous wave (FMCW) radar have become common place in many roadside trac and on board vehicle safety systems. The accuracy in these systems is based on the underlying calibration of these sensors, which can be a time consuming and costly process. In our approach, using an uncalibrated commercial- o-the-shelf (COTS) radar sensor, vehicles were monitored along a roadside. A moving target indication (MTI) technique is used to reduce background clutter with thresholding and CFAR techniques used for signal detection. These detections are fed into an extended Kalman lter, and using dierent association approaches, the results are compared to GPS ground truth.
