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 370 meters 92 meters 46 meters
Person 1303 meters 325 meters 162 meters
Vehicle 3156 meters 789 meters 394 meters

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