POCKET RADAR™
Radar Measurement Challenges
Due to the nature of how Doppler speed radar works, all speed radars will only measure the
relative speed of a target in the direction that it approaches or moves away from the speed
radar. The Pocket Radar™ will measure speed most accurately when the path of the moving
target runs directly in-line with the beam of the radar. (Note: Always be safe. Never put
yourself in a position where you could be struck by a moving object.) If you point the beam
of the Pocket Radar™ even a slight angle sideways to the path of the moving object, you
will measure a slower speed than the object actually travels along its path. You will also find
it more difficult to time the measurement and capture the object within the narrow beam of
the radar when you measure off angle. (Think of the beam like a flashlight beam, not like a
floodlight).
