| Abstract: | Based on Doppler effect,given both observed frequency f and emitted frequency f0,as well as the velocity of waves in the medium v,the velocity of the source relative to the medium vs can be determined where the receiver keep still relative to the medium.The experimental device,take MCU as the core of Measuring and Controlling system,can demonstrate experiment of ultrasonic Doppler effect and test the speed of moving objects by frequency measuring.Design details were provided.Both experimental results and its relative analyses were presented.The instrument features its soft-core,which made device be able to easily remodeling and extensibility. |
