As seen in "MythBusters: Beat the Radar Detector"
Hemera

Finding: BUSTED

Explanation: One of the most feared weapons in a police officer's arsenal is the dreaded radar gun. By firing at passing cars with microwaves that then bounce back at different frequencies, the devices detect whether drivers are cruising over the speed limit.

MythBusters Tory Belleci, Kari Byron and Scottie Chapman tried out a lineup of supposed radar gun-dodging tricks, including jingling keys at the radar gun; hanging disco balls and CDs from rearview mirrors; installing LED light license plates; and covering hubcaps and an entire car in aluminum foil. The team also assembled a microwave gun and aluminum foil-shooting gun meant to scramble the police radar gadgets. As a last resort, the MythBusters even covered their test Cadillac in matte black paint in hopes of sneaking it past the radar undetected.

But as the MythBusters suspected, none of these stealth tactics helped them give the radar gun the slip.

Let the busted myth be a lesson to lead-footed folks everywhere — the only surefire way to pass by police speed guns without getting caught is to drive the speed limit.
