This paper describes the verification test on Electromagnetic Environmental Effects(E3), which conducted on ground as a final step to confirm the normal operation of ELINT pod and Safety-of-Flight of KF-16C/D mounted with ELINT pod prior to the initial flight. Based on MIL-STD-464A, indispensable 7 requirements among 14 detailed requirements total were carried out in the test. Considering the Safety-of-Flight(SOF), we invest a great deal of time and effort on Hazards of Electromagnetic Radiation to Ordnance(HERO) and Intra-system EMC test. E3 test and evaluation were performed on 62 equipments of KF-16C/D, respectively. As a result, we verify that KF-16C/D mounted with ELINT pod(hereafter "system") are electromagnetically compatible among all subsystems and equipment within the system and with environments caused by electromagnetic effects external to the system.

This paper presents guidelines for the verification test on electromagnetic environmental effects of a commercial derivative military aircraft. To prove the safety-of-flight of a renovated aircraft and appropriate working of electronic system/device, E3 test and analysis at the system level should be performed prior to its operations on real warfare. For the aircraft modified with Falcon 2000S, we concentrate on intra-system EMC, EMRADHAZ (Electromagnetic Radiation Hazards), electrical bonding, P-Static as test and lightning as analysis from a airworthiness certification point of view based on MIL-STD-464, MIL-HDBK-516. As a result, it is verified that the modified aircraft has enough electromagnetic compatibility capabilities under EME(Electromagnetic Environment). In the process, test and analysis methods considering shielding effectiveness(SE) are applied.

본 연구에서는 항공기에 장착하여 S/C대역의 신호를 장거리 표적으로 방사하기 위한 장치를 개발하였다. 장치는 요구된 실효 등방성 복사전력을 충족시키기 위해 대역별 송신기와 광대역 안테나로 RF 인터페이스를 구성하였다. 장치의 외형은 항공기 연료탱크와 동일한 포드(pod) 형상으로 설계했고, 측정된 장치의 중량은 119.8 kg, 무게중심은 1391.35 mm 그리고 관성 모멘트는 46.07 ± 0.05(I_yy) kg·㎡과 45.36 ± 0.09(I_zz) kg·㎡로 모두 항공기 장착을 위한 요구도를 충족함을 확인하였다. 비행 안전을 확인하기 위해 전자기 간섭 시험(RE102, CE102), 환경시험(고온/저온 운용, 고도), 체계 내 전자기 적합성 시험 그리고 인체 전자기 복사 위해도 시험을 수행하였으며, 모든 항목의 시험 결과가 요구사항을 충족함을 확인하였다. 장치는 요구되는 전기적/기계적으로 요구되는 사항을 모두 충족함으로써 항공기 장착이 가능함을 확인하였다.
