What are the three basic steps in the identification process of a typical IFF system?

In the identification process of a typical Identification Friend or Foe (IFF) system, the correct sequence involves a critical interaction designed to ensure the distinction between friendly and hostile forces. The fundamental steps consist of challenging the target, decoding the received response, and prompting a reply.

The challenge step initiates the process by sending a signal to the target, asking for identification. This is essential for determining whether the responding entity is friendly or not. Following this, the decode step involves interpreting the response received from the target, often utilizing specific codes or signals that signify its status. The final step is the reply, where the target acknowledges the challenge and provides its identity, confirming or denying its friendly status.

This sequence is crucial for maintaining situational awareness and ensuring effective communication during operations, supporting the overarching goal of enhancing safety and coordination among forces.
