Abstract

The effect of new building on the HF direction finding(DF) is analyzed. Commercially available software is used to get array manifold of the HF DF system. The terrain, building and the array antenna system are modelled. New building near the antenna system is also modelled to see whether it actually has an effect on the performance of the DF system. MUSIC and interferometer DF algorithms have been employed.

신규 건물에 의한 HF 대역 방향 탐지 왜곡 여부를 알아보기 위하여 상용으로 사용 가능한 전자기 산란 프로그램을 이용한다. 지형, 건물, 안테나 시스템 등이 포함된 모델을 이용하여 어레이 매니폴드를 구한다. 안테나 시스템 주변의 신축건물이 존재 시 안테나 응답을 이용하여 신축건물에 의한 방향 탐지 영향 여부를 조사한다. 방향 탐지 알고리즘은 MUSIC과 interferometer를 이용하였다.
