Abstract

In this research, we develop an airborne equipment radiating S/C-band signal to a target located at a long distance. RF interface of the equipment comprises band-specific transmitters and an broadband antenna to satisfy EIRP(effective isotropic radiated power) requirements. The equipment is in a shape of a POD like an aircraft fuel tank. The measured weight of the equipment is 119.8 kg, the CG(center of gravity) is 1391.35 mm and the MOI(moment of inertia) are 46.07 ± 0.05(Iyy) kg·㎡, 45.36 ± 0.09(Izz) kg·㎡. All results are found to meet the requirements for aircraft installation. To verify flight safety, EMI(electromagnetic interference) tests (RE102, CE102), environmental tests (high/low temperature operation, altitude), intra-system EMC(electromagnetic compatibility) and HERP(hazards electromagnetic radiation personnel) tests have been conducted and all the test results met the requirements. It is confirmed that the equipment could be mounted on the aircraft by meeting all electrical and mechanical requirements.

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(Iyy) kg·㎡과 45.36 ± 0.09(Izz) 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.
