MUM-T 탑재 안테나 소형화/경량화를 위한 소요제원 최적화 설계 방안 = The Optimized Design Method of Required Specification for the Downsizing/Lightweight of MUM-T Mounted Antenna

국문 초록 (Abstract)

최근 유․무인복합체계(MUM-T) 기술의 중요성이 강조되고 있는 군에서는 안정적인 데이터링크를 제공하면서 항공기에 탑재가 용이한 소형화 및 경량화된 안테나의 필요성이 증가하고 있다. 이를 위해서는 시스템 설계에서 합리적인 분석을 통해 불필요한 마진을 최소화하는 소요제원 최적화가 필수적이다. 본 논문에서는 안테나의 소요제원을 최적화하기 위해 시스템의 링크버짓 및 타겟 플랫폼의 기동특성을 고려하여 기계적 측면에서 안테나 구동부에 소요되는 구동제원과 전자기적 측면에서 안테나 방사체에 소요되는 3dB 빔폭제원을 획득하는 방법을 제안한다. 아울러, 이를 토대로 현재 개발 중인 제품과 이전에 개발이 완료된 유사 제품의 제원 비교를 통해 소형화율 및 경량화율을 산출하여 최적화 수준을 평가한다.

In the military, where the importance of Manned-Unmanned Teaming(MUM-T) technology has recently been emphasized, the need for a downsizing and lightweight antenna that can be easily mounted on aircraft while providing stable data-link is increasing. To meet this demand, it is essential to optimize the required specifications by minimizing unnecessary margins through reasonable analysis at the system design. In order to optimize the required specifications of the antenna, this paper proposes a method of obtaining the driving specifications required for the antenna drive unit from the mechanical viewpoint and the 3dB beam width specification required for the antenna radiator from the electromagnetic viewpoint in consideration of the system link budget and the movement characteristics of the target platform. In addition, the level of optimization is evaluated by calculating the downsizing rate and the lightening rate through comparison of the specifications of the product that is currently under development based on the proposed method and the similar product that was previously developed.
