A radar-based identification system developed for command and control is called Identification friend or foe (IFF). It makes use of a transponder that responds to an interrogation signal and identifies the broadcaster. Electronic devices known as Identification Friend or Foe (IFF) Interrogators send out a radio signal that is referred to as an “interrogating” signal on one frequency.
This causes an IFF Transponder to send out a reply signal on a different frequency, which tells the IFF Transponder that an approaching aircraft is “friendly.” The identification system known as Identification Friend or Foe was developed for command and control purposes.
It enables interrogation systems for military and civilian air traffic control to identify friendly aircraft, vehicles, or forces, as well as their bearing and range from the interrogator.
The Air Traffic Control (ATC) System, which is used to identify and track military aircraft, is referred to by the military as IFF (Identification Friend or Foe). An airborne transponder and a ground (or airborne, or shipborne) interrogator make up the IFF system. The working principle is actually quite straightforward: An encoded radio signal is sent to the aircraft by an IFF interrogator. In order to signal that it is friendly, the aircraft’s specialized IFF transponder responds to the signal.
The Global IFF Test equipment 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.
The U.S. Department of Defense (DOD) Air Traffic Control Radar System (ATCRBS), Identification Friend or Foe (IFF), Mark XII/XIIA, Systems program office, more commonly referred to as AIMS, has granted certification to the Aeroflex APM-424(V)5 identification friend or foe (IFF) portable test set from Aeroflex Test Solutions in Wichita, Kansas, for use in flight-line testing of IFF transponders and interrogators.
Aeroflex APM-424(V)5 avionics ramp test equipment is certified by DOD to meet DOD AIMS 03-1000A performance standards. Air traffic controllers use the encrypted aircraft identification system known as IFF Mode 5 to distinguish between friendly aircraft, vehicles, or forces, as well as their travel direction and distance from the interrogator.
Aeroflex officials claim that the APM-424(V)5 is a lightweight flight line test set designed for non-commercial pre-mission testing of IFF transponders and interrogators. It uses secure IFF Mode 5 to test development. Time of day authentication, spread spectrum modulation, and improved encryption are features of Levels 1 and 2.
