To capture the speed you are travelling, the Police often use bulky radar guns. Pocket Radar is a new system that achieves the same as a large radar gun, but this one fits in your pocket.
The Pocket Radar system can capture speeds of various objects including people, cars, baseballs, football and more and can track speed to within 1MPH +/-. The device uses a set of AAA batteries to run which thanks to energy efficiency allow up to 10,000 measurements to be captured before having to get new batteries.
The Pocket Radar system uses a Doppler radar signal detection to capture the speed of moving objects with the added bonus of it being pocket size. The device will on show in a few weeks time at CES 2010 with the system being made available later on in 2010 around Spring time.
