IFF system for infantry

This project implements an Identification Friend-or-Foe (IFF) system for use by soldiers to prevent friendly-fire. The inspiration for the project is derived from Identification Friend-or-Foe (IFF) transponder systems currently used on fighter aircraft and military vehicles. Fighter aircraft fitted with an IFF system transmit a coded radio (RF) message to other aircraft detected within a pre-set range. Friendly aircraft can decrypt the RF message and provide a correctly encrypted response to prevent fratricide.
