That gives the photons an APPARENT higher oscillation frequency. Atoms in the vehicle send photons with that higher oscillation frequency back to the radar gun. Those photons also travel at c. The radar gun compares the oscillation frequency of the photons it emitted to the oscillation frequency of the photons it got back and is thus able to compute the speed of the oncoming vehicle.

To meet this requirement, one of the simplest designs, called the homodyne radar, has been used for all police radar designs since the late 1940 time period. Figure 16-2 is a block diagram showing the homodyne concept".

c’=c{(transmiting frequency - returning frequency)}/transmiting frequency

All of ten milliseconds before the tail end of the plane crashes in on
the 'smart' athlete, smashing him to smithereens.

Too bad you were not on board of Germanwings Flight 9525,
to tell us about what happened onboard,
