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 195 meters 48 meters 24 meters
Person 686 meters 171 meters 85 meters
Vehicle 1661 meters 415 meters 207 meters
