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 201 meters 50 meters 25 meters
Person 707 meters 176 meters 88 meters
Vehicle 1713 meters 428 meters 214 meters
