Leonardo Studies E-scan IFF For Typhoon
Leonardo has developed an innovative IFF arrangement to complement the AESA radar

Leonardo-Finmeccanica is undertaking a TDP (technology demonstrator program) on behalf of the UK Ministry of Defence to study a new IFF system for the Eurofighter Typhoon that incorporates active electronically-scanned antenna technology. The study follows on from development of a similar system for the Saab Gripen E, and is aimed at not only upgrading the Typhoon’s existing IFF functions, but also preparing it for installation alongside the Captor-E “e-scan” radar. In any case, Typhoon is due for an IFF upgrade to meet civilian Mode S requirements in 2017, and military Mode 5 needs in 2019.

Based on the M248 transponder and SIT 2010 crypto equipment, the “e-scan” installation is to be placed in the Typhoon’s wingroots, from where the antennas can scan more than 180 degrees. In the Gripen E installation, they are distributed around the forward fuselage.
