The main objective of this paper is to design the vehicle speed measuring system with the help of Doppler shift frequency and offset angle of sensor related to direction of object motion and to verify the ability of the system in performing a better utility ground based speed measurement device, is the intention of this work. The non-contact Doppler sensor requires extremely high installation accuracy, and its speed-measuring error is nonlinear and uncorrectable without offset angle. The non-contact sensor could measure the speeds of both forward and reverse motions, including low speed motion with high accuracy. The method proposed for speed measuring system is good platform than other system which are complex and costly.
