Abstract

In this study, we present a method for verifying the performance of an antenna used in an aircraft. Identification friend of foe equipment requires the AIMS certification of the US Department of Defense for interworking with the encryption device; the performance of IFF is verified through the verification process of DoD AIMS 1102 and DoD AIMS 1103 according to an aircraft model equipped with a transponder. It was determined whether the performance standards of the antenna and radiation pattern were met, and whether the aircraft that did not meet the required performance met the performance by replacing or additionally installing the antenna. After submitting the DoD AIMS 1102 requirement test documents and completing the preliminary preparation for the DoD AIMS 1103 verification, the antenna performance was verified not only in Mode 5 but also in the SIF mode through flight tests. Through the process of meeting the AIMS certification requirements, the performance verification of IFF was confirmed, and it is expected that it can be used for the verification of avionics antennas such as communication and navigation.
