DRI Ranges

DRI stands for Detection, Recognition and Identification and is based on the widely used Johnson's criteria.

  • Detection Detect if an object is present
  • Recognition See what type of object it is (i.e. person, vehicle, airplane)
  • Identification For example see if someone is a friend or foe
Detection Recognition Identification
Rabbit 150 meters 37 meters 18 meters
Person 527 meters 131 meters 65 meters
Vehicle 1277 meters 319 meters 159 meters

Please note that these values are calculated, always consult the manufacturer for official range numbers.
