The talk will cover how SSR and IFF work including the Uplink and ground link aspects and the implementation and real-world deployment issues associated with secondary radar. The migration to a specific and recent development of secondary radar known as Mode S is explained covering the benefits brought by its introduction and the effects of the environment on the signal in space.
