The Accuracy of the Doppler Shift Equation

The objective of our experiment was to prove the accuracy of the Doppler effect equation. We used a deer whistle to generate a constant frequency and investigated pitch changes as the whistle was moved toward a detector or when a detector was moved toward the whistle. Then we used the Logger Pro Software to generate a Fast Fourier Transfer to determine the frequency of the shift of the whistle due to the Doppler shift equation. Comparing our data to the expected values, we calculated the error of our data to be between .041% and 3.1%, error we determined to be small. With this small of an error, we believe that a collision avoidance system based on the Doppler shift of a given frequency is feasible.
