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 264 meters 66 meters 33 meters
Person 931 meters 232 meters 116 meters
Vehicle 2254 meters 563 meters 281 meters

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