Pocket Radar™ products utilize a Doppler radar signal sensing and processing system coupled with re-engineered microwave and antenna components to deliver powerful performance into devices compact enough to easily fit into a shirt pocket.
In creating the world’s most compact speed radar devices, we had to completely re-assess, re-engineer and re-build nearly every aspect of traditional radar technology. By combining Pocket Radar’s proprietary digital signal processing algorithms and state-of-the-art intelligent target acquisition techniques we are able to provide users with industry leading accuracy and speed measurement into devices that are a tiny fraction of the size of traditional speed radar guns.
From the world’s smallest certified accurate speed radar, to the only radar gun specifically designed for coaching and training, Pocket Radar has engineered a revolutionary product line to fit your speed measurement needs. Each Pocket Radar design includes exceptional performance and technology that fits in the palm of your hand. Pocket Radar products are convenient and rugged enough for everyday use by everyone from pro to amateur, to National Championship winning coaches and anyone interested in speed.
How It Works
Pocket Radar products are Doppler speed radar systems.
They work as a speed detector by emitting a small pulse of radio waves in an invisible focused beam, similar in shape to a flashlight beam.
When the radio wave hits an object that is moving towards or away from any of the Pocket Radar’s, a small amount of the wave reflects back.
The moving object modifies the reflected radio wave based upon how fast it is moving directly towards or away from the Pocket Radar unit.
The unit then receives the reflected radio wave and compares it to the original transmitted radio wave. It then calculates the speed of the moving object based upon the difference between the two radio waves.
Note that each Pocket Radar model, like all Doppler speed radars, can only measure the speed of a moving object that is reasonably close to in-line with the direction of the radio wave beam. They cannot measure any motion side to side, across the radio wave beam. (NOTE: Never put yourself or others in a position where anyone could be hit by the moving object!)
The focused beam comes from the radar lens on the back of the unit directly behind the display.
