Hello,
I did not, but I measured doppler using a pendulum and two smartphones with independent measurements of the velocity by the gyroscope of the smartphone on the pendulum. Smartphone on the pendulum measured the Doppler frequency shift and a second smartphone was used as generator of 1000 Hz sound. A time shift between two signals had to be compensated...
