A concept of GSM-based passive radar for vehicle traffic monitoring

In this paper the passive radar used as a transmitter of opportunity GSM BTS stations has been proposed for vehicle traffic monitoring. The paper presents a feasibility study on using GSM signals for traffic control in different environments including urban areas, highways and small agglomeration roads. The initial analysis shows that such system can be successfully used to extract traffic parameters such as the average speed of vehicles and road capacity. Additionally, the presented GSM passive radar concept for vehicle traffic monitoring has been successfully verified using real-life signals recorded during a measurement campaign carried out at the Warsaw University of Technology.
