Other AbstractIn order to verify the reliability of the velocity measurement by microwave modulated laser technologies, a system of microwave modulated laser velocity measurement was developed. In the system, laser as carrier was intensity-modulated by microwave signal, transmitted the signal intensity was directly detected by the receiver on a movement platform. After the signal processing, the Doppler frequency shift data was obtained, from which the relative velocity was obtained. Meanwhile, the average velocity as the third party data was calculated by measurements of the movement distance and time, which was used to compare with velocities calculated by Doppler shift. The theoretical analysis and verification experiment are presented and the results show that the velocities calculated by Doppler shift are in good agreement with the third party velocities with a mean deviation of 2.0%.
