초록

본 논문은 항공용 다변측정 감시시스템의 감시영역으로 진입하는 항공기에 대해 능동적 공역확보를 위한 질문시나리오 구성이 가능한 질문기에 대한 것이다. 항공용 다변측정 감시시스템에서 질문기는 감시공역 내의 항공기를 향해 적절한 감시 시나리오로 질문을 수행하는데 사용하는 중요한 장치이다. 일정 반경 내에서 비행하는 항공기에 대해 질문하는 기존의 2차 감시레이다 (SSR; secondary surveillance radar)의 질문 방식과 달리, 항공용 다변측정 감시시스템은 감시범위에 진입하는 항공기에 대해 원거리에서 부터 근거리까지 순차적으로 또는 운용 시나리오에 따라 능동적으로 질문이 가능한 질문 시스템이 필요하다. 본 논문을 통해 구현된 질문기는 위스퍼-샤웃 제어 알고리즘을 적용하여 실제 운용거리에 따라 출력전력을 가변하여 방사함으로써 감시공역 별 항공기에 대한 질문 및 감시에 능동적으로 활용이 가능하다.

This paper is concerned with an interrogator capable of constructing a interrogation scenario for acquiring active airspace to the intruding aircraft into the surveillance area of the MLAT system. In the MLAT system, the interrogator is an important device used to carry out the interrogation towards the aircraft within the surveillance airspace in the appropriate surveillance scenario. Unlike a conventional SSR's interrogation methods that interrogate for airplanes flying within a certain range, the MLAT system requires a interrogation system that can actively interrogate from remote to near range, or according to operational scenarios, for aircraft intruding into the surveillance range. The interrogator implemented in this paper can be used for interrogating and monitoring aircraft within each surveillance airspace using whisper-shout algorithm according to varying output power based on the actual operation distance.
