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
