Relativistic Beaming

When a star or other light-emitting object is moving close to the speed of light relative to an observer, it exhibits something called "beaming". Even though an observer moving the same speed as the star would see light emitted in all directions, if the star is moving, the light gets more focused in the direction of motion.

This animation shows relativistic beaming for a star moving to the right, relative to an observer (us). Each second of the animation increases the star's relative velocity by 10% of light-speed, ending when the star is moving 99% of the speed of light. I also included a (highly inaccurate) depiction of the Doppler effect, wherein observers will see the light's wavelength decrease - blueshift - if the star is moving toward them, while if the star is moving away, they will see a redshift.

What if the object is REFLECTING photons? If you painted a near-light-speed object with a radar, wouldn't the reflected energies be focused in the forward direction of travel, too?

So, if you painted a near light speed object with radar, it would reflect the light blue-shifted to gamma rays in the forward direction, x-rays somewhat off to the sides, and so on around (through UV, visible, IR, millimeter, microwave, radio) in the reverse direction?
