Abstract: According to the characteristics of uniform circular motion,the Doppler effect of high frequency wave for three different motion states,such as wave source fixation and observer movement,wave source motion and observer fixation,both wave source and observer movement,are discussed,respectively.The generalization of both wave source and observer move in different circle and direction of different circular motion is derived in different relative motion state to receive the wave frequency formula.The results show that the frequency of the received wave is periodically changed in the uniform circular motion state,and the frequency of the received wave's frequency change is positively correlated with the absolute value of the angular velocity difference of the wave source observer. The magnitude of the received wave frequency is affected by the angular velocity difference,the absolute value,the observer's radius of motion and the wave velocity,but the effect is different,while the extreme point position is affected by the wave source radius of motion.

Key words: Doppler effect, uniform circular motion, high frequency wave, wave source, observe
