I dont quite remember Einstein's stuff on this.

Hi Bob,

Actually it was Lorentz.

Since though I
doubt I'll never get to experiment with it I dont need to go through it
again!

Not hard to do if you think in terms of a Klystron tube. Although it
might not directly use Doppler within the stretch of its beam current,
the tube structure is quite decidedly built for speed of light and
wavelength bunching. Hop in a car with one and you got your 100 kM/h.

Walla (as the french say) you've built your own speed trap radar
beacon.
