Research on Microwave Velocimetry Sensor System for Claw Passenger Trucks

LI Fuwei, ZHAI Shouzhong, HU Fengzhong (Changsha Institute of Mining Research, Changsha 410012)  
This paper describes research on X-band doppler sensor system, used to measure the speed of claw passenger trucks. Considering cost efficiency and miniaturization, we incorporated oscillation and mixing in the structure of a single cavity. In this design, the systems oscillator and mixers are completed by different device, so the usual problems associated with transmitter power and mixing efficiency are resolved. Using multi-sensor principle, a sensor system is installed, including a transceiver and receiver in front-end, which transmits and receives microwave signal from the back-bottom of the claw passenger truck. Using echo signal processing greatly improves the measurement accuracy of system.
