Identification, friend or foe ( IFF) is a combat identification system designed for command and control. It uses 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. [ 1]
IFF Mark X was the NATO standard military identification friend or foe transponder system from the early 1950s until it was slowly replaced by the IFF Mark XII in the 1970s. It was also adopted by ICAO, with some modifications, as the civilian air traffic control (ATC) secondary radar (SSR) transponder. The X in the name does not mean "tenth ...
The aviation transponder interrogation modes are the standard formats of pulsed sequences from an interrogating Secondary Surveillance Radar (SSR) or similar Automatic Dependent Surveillance-Broadcast (ADS-B) system. The reply format is usually referred to as a "code" from a transponder, which is used to determine detailed information from a ...
Interface force field. In the context of chemistry and molecular modelling, the Interface force field (IFF) is a force field for classical molecular simulations of atoms, molecules, and assemblies up to the large nanometer scale, covering compounds from across the periodic table. [ 1] It employs a consistent classical Hamiltonian energy ...
It also incorporated the new AIMS IFF for air control of friendly aircraft, and a Low Flier Detection Mode (LFDM). [1] Field change 8 for the SPS-40B/C/D versions introduces a Digital Moving Target Indicator (DMTI), which automatically eliminates unwanted clutter, selecting only objects with some minimal radial velocity as targets.
Combat Identification Panel. The Combat Identification Panel ( CIP ), also known as a Coalition Identification Panel, is an Identification friend or foe device mounted on military ground vehicles used by United States Armed Forces ' United States Army with United States Marine Corps and its allies to distinguish them from the enemy during battle.

IFF Mark III, also known as ARI.5025 in the UK or SCR.595 in the US, was the Allied Forces standard identification friend or foe (IFF) system from 1943 until well after the end of World War II. It was widely used by aircraft, ships, and submarines, as well as in various adaptations for secondary purposes like search and rescue . 500 units were ...
