Oscillating charge, wave shift

  1. May 5, 2008 #1
    Consider a charge oscillating along the Y axis. EM waves are emitted around it and hits an observer further down the X axis. The charge then gains speed along the X axis, moving towards the observer. He notes a blueshift in the measured EM wave, ie the Doppler effect.

    My question is... Will any movement of the charge along the X axis, no matter how small, shift the wave measured by the observer?
