Identification, friend or foe (IFF) is a command and control-focused identification system. It employs a transponder that searches for an interrogation signal before responding with information about the broadcaster.
IFF systems typically employ radar frequencies, but they can also use radio or infrared frequencies. It makes it possible for military and civilian air traffic control interrogation systems to distinguish between friendly and neutral or hostile aircraft, vehicles, or forces and to calculate their bearing and range from the interrogator.
Transponders used to identify a boat as “friendly” by responding to “interrogation” signals sent out by IFF system Interrogators are known as Identification Friend or Foe (IFF) Transponders. They are transmitter/responders mounted on aircraft, naval vessels, and some ground vehicles.
Only positively identified aircraft or other forces can be used by IFF. Friendly forces may not properly respond to IFF for a variety of reasons, such as equipment malfunction, and parties in the area not involved in the combat, such as civilian airliners, will not be equipped with IFF.
If an IFF interrogation receives no reply or an invalid reply, the object is not positively identified as a foe. IFF is a technology used in the larger military operation known as Combat Identification (CID), which is the accurate characterisation of items found in the field of battle to support tactical decisions.
The four categories of friend, foe, neutral, and unknown are the broadest. In addition to decreasing friendly fire events, CID also influences overall tactical judgement.
The Global IFF secondary radar market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Sensor solutions specialist HENSOLDT has achieved a major technology development milestone which substantially enhances the detection capabilities of Ground-based Air Defence (GBAD) systems.
The company implemented and tested successfully a software enhancement with its proven MSSR 2000 ID secondary radar that allows for precise tracking of aircraft in addition to the conventional surveillance mode of Identification-friend-or-foe (IFF) systems.
A so-called “stop & stare mode” allows GBAD systems to process identification tracks in specific sectors in near-realtime and very precisely. The new feature enables the user to switch from a fairly routine surveillance operation to a laser-focused lock-on and track mode.
using electronic beam steering and automated antenna control. By doing this, the process of differentiating between friendly and enemy troops is greatly quickened, greatly improving the protection of ground forces.
By automatically delivering interrogation signals that are responded to by transponders on friendly aircraft, IFF systems precisely identify aircraft. As a result, IFF aids in preventing incidents of friendly fire by allowing field commanders to discriminate between friendly and hostile forces.
In order to prevent hostile signal modification, the most contemporary “Mode 5” IFF systems, like MSSR 2000 ID, use sophisticated encryption algorithms. As a result, the identification procedure is completely trustworthy and safe.
