Interrogator-Transponder Set

An Interrogator-Transponder Set, also known as an IFF (Identification Friend or Foe) system, is a communication system used in military and aviation applications. It consists of two main components: the interrogator and the transponder.

The interrogator is a device that sends out radio frequency signals to identify and communicate with other aircraft or vehicles. It transmits coded signals and receives responses from transponders.

The transponder, on the other hand, is a device installed on an aircraft or vehicle that receives the signals from the interrogator and responds with a unique identification code. This code helps to identify the aircraft or vehicle as a friendly entity.

The purpose of an Interrogator-Transponder Set is to enhance situational awareness and prevent friendly fire incidents. By using this system, military personnel and air traffic controllers can quickly identify and differentiate between friendly and hostile aircraft or vehicles.

IFF systems are widely used in military operations, air traffic control, and civilian aviation to ensure safe and efficient communication and identification of aircraft.
