How does IFF radar work?
The principle of operation is really quite simple: an IFF interrogator sends out a coded radio signal to the aircraft. A special device on the aircraft, an IFF transponder, picks up the signal and sends a response to identify itself as friendly.
How do planes show up on radar?
A radar system detects other aircraft, ships, or other objects and the speed and direction in which they travel by sending out a pulse of high-frequency electromagnetic waves. This pulse goes out ahead of the aircraft until it encounters an object and reflects off of it.
What does IFF mean on aircraft?
Identification Friend or Foe is an identification system designed for command and control. It enables military and civilian air traffic control interrogation systems to identify aircraft, vehicles or forces as friendly, and to determine their bearing and range from the interrogator.
Can IFF be spoofed?
IFF technology, which helps radar operators and missile crews tell the difference between friendly and potentially hostile aircraft, can be susceptible to spoofing, so securing this capability is essential.
What is an IFF interrogator?
Identification Friend or Foe (IFF) Interrogators are electronic devices that emit an “interrogating” radio signal at one frequency, prompting an IFF Transponder to emit a reply signal at a different frequency, indicating that an approaching aircraft is “friendly.”
What are the different modes of IFF?
IFF is used by both military and civilian aircraft. Modes 1, 2, 4 and 5 are for military use only. Modes 1, 2 and 3/A are collectively known as Selective Identification Feature (SIF) modes. Civilian aircraft use modes 3/A, C and S.
How are planes identified?
Each Mode S-equipped aircraft has a unique, permanent identification number that remains during the life of the aircraft. Once an air traffic control computer identifies an aircraft by its address, that aircraft goes into a “roll call.” Subsequent interrogations are transmitted on a schedule.
What is aircraft identification?
Pilots and ground personnel use the phonetic alphabet to help them understand each other. In addition, all airplanes must have an identification number. This is much like an automobile license tag. Each number starts with a letter to identify the country.

What is Mark XII IFF?
The Mark XII IFF System is a cooperative question and answer friend identification system that has been operational since the 1960s. platforms will be via a cost-effective evolutionary upgrade to modern digital IFF hardware. The Mark XIIA Mode 5 Program stems from the DoD Mark XII Improvement Initiative begun in 1995.
What is selective identification feature?
A capability that, when added to the basic identification friend or foe system, provides the means to transmit, receive, and display selected coded replies. Dictionary of Military and Associated Terms.
