Using a dedicated radio beacon, the Belgium radio-meteor observers have made a simultaneous observation of the same meteor from six locations. The images show the spectrum of the received audio signal. The transmitter transmits an unmodulated signal and the displacement of the received signal, in the vertical axis, is due to the Doppler shift resulting from the movement of the reflecting surface.
The technical details of the observation are shown below.
