Recent statement states that the Norwegian armed forces will be receiving upgraded Identification-Friend-or-Foe (IFF) technology as part of a contract worth $15 million with the German company Hensoldt. 

“The IFF systems working according to the latest Mode 5 NATO standard will be integrated into land installations in order to improve their ability to distinguish friendly from hostile forces,” the company stated.

IFF systems, or Identification friend or foe, are identification systems designed for command and control. They use a transponder that listens for an interrogation signal and then sends a response that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. 

According to militaryembedded.com, The IFF systems, also known as secondary surveillance radars (SSR), automatically send interrogation signals to aircraft in the area, which the friendly aircraft respond to via their on-board transponders. Mode 5 uses stronger encryption than Mode 4 to avoid signal manipulation from an adversary.
