A novel dual microwave Doppler radar based vehicle detection sensor for parking lot occupancy detection

Abstract

This paper described a novel vehicle detection sensor design in which dual microwave Doppler radar transceiver modules were used to detect the movement of a parking vehicle. A motion recognition algorithm was also presented to identify the vehicle behavior and generate the parking space occupancy status. Comparing with existing methods such as magnetometer and optical based detection, the proposed design simplified engineering integration from complex optical system design as well as achieved a high detection accuracy. Experimental results showed that the proposed dual microwave Doppler radar sensor detected the vehicle movement clearly and the parking space occupancy detection accuracy was higher than 98%.
