초록

입사 신호에 대한 배열 안테나의 응답인 array manifold를 측정에 의해 생성하는 방법을 기술하였으며, 기술된 방법에 의해 실측된 등간격 원형 배열 안테나의 array manifold를 MUSIC 알고리즘에 적용하여 배열 안테나로 입사되는 300 MHz tone 신호의 공간 스펙트럼을 추정하였다. 측정 array manifold를 이용한 공간 스펙트럼 추정은 이상적인 배열 안테나를 가정한 계산 array manifold 대비 월등한 성능을 보인다.

A method for measuring array manifold which is the array antenna response of incident signal is presented. Array manifold measurement procedure by the presented method is explained for UCA(Uniform Circular Array), and spatial spectrum of 300 ㎒ tone signal incident on UCA is estimated by MUSIC algorithm in which spatial spectrum peak is searched with measured array manifold. Spatial spectrum estimation using array manifold measured by the proposed method shows superior performance to calculated array manifold.
