Abstract
This paper proposes an effective method to detect the passive tag's velocity. When a tag is moving, the energy distribution between received baseband signal I and Q changes over time as a result of both the Doppler Effect and the change of distance between reader and tag. Without any modification of the antenna, only one conventional reader was used to detect the change of distribution to calculate the velocity. This method was proved effective in the laboratory environment and it has great potential to be applied in the highway vehicle speed system in the future.
