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 285 meters 71 meters 35 meters
Person 1002 meters 250 meters 125 meters
Vehicle 2427 meters 606 meters 303 meters

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