IFF (Identification Friend or Foe)

Identification Friend or Foe (IFF) is a technological system used primarily by military and aviation authorities to determine whether a nearby object is a friendly or threat. It works through radio signals exchanged between an aircraft or ship and a dedicated IFF system. When a friendly vehicle sends a specific code, the IFF system recognizes it as safe, helping to prevent friendly fire incidents. IFF systems are crucial for situational awareness, enabling quick identification in complex environments while reducing the risk of misidentification and enhancing operational safety.
