An Application of a Low-Cost Microwave Radar to Traffic Monitoring

The paper proposes an approach for acquiring traffic data with a microwave technology-based movement sensor. Our aim is to detect the vehicles, their speed and the direction-of-arrival at the observation point, using the Doppler principle and the analysis of sensor signal spectrograms. Experiments on data collected from real traffic confirm the feasibility of the approach, showing near 95% detection rate, near perfect direction-of-arrival detection and adequate velocity estimation.
