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 525 meters 131 meters 65 meters
Person 1847 meters 461 meters 230 meters
Vehicle 4472 meters 1118 meters 559 meters
