Velocity evaluating of the moving objects

The paper deals with methods of contactless tachometry by radar sensors. The radar sensors are characterized by a good reliability and relatively high accuracy of measurements. The goal of the paper is to propose and realize the system which would manage to measure moving objects with a pulse radar and the Matlab software. Measuring of moving objects has been realized through the radar sensor which operates in an X-frequency band. The audio output of the radar sensor has been used for the velocity measurement and for the signal processing, a PC sound card and Matlab DAQ libraries have been used.
