USV(Universal Steering Vector)를 사용한 MUSIC 기반 DOA(방향 도착 방향) 추정이 실험적으로 연구되었습니다. 실험에는 4소자 어레이 안테나와 4채널 수신기가 사용되었습니다. DOA 추정의 정확성을 높이기 위해 배열 요소 간의 상호 결합 효과와 배열 요소 자체의 효과를 이미 포함시킨 USV를 보상하여 수신기의 4개 채널의 전기적 지연 및 손실을 더 포함시킵니다. 본 논문에서 제안하는 보상된 USV(C-USV) 접근법은 USV에 대한 보상 행렬이 S 급전 케이블의 RF 입력 포트와 수신기의 IF 출력 포트 사이의 매개변수입니다. MUSIC 기반 DOA 추정의 실험 결과는 C-USV 접근법이 MUSIC 기반 DOA 추정을 위한 정확하고 효과적이며 실용적인 방법임을 보여줍니다.

Abstract: MUSIC-based estimation of direction of arrival (DOA) using universal steering vector (USV) is experimentally studied. A four-element array antenna and a four-channel receiver are employed for the experiment. In order to improve the accuracy of DOA estimation, USV which has already included the effect of mutual coupling between array elements and effect of array elements themselves is compensated to further include the electric delay and loss of four channels in the receiver. The compensated USV (C-USV) approach proposed in this paper does not need the time-consuming measurement of array element pattern because the compensating matrix for USV is obtained by measuring the S parameters between RF input ports of the feeding cables and IF output ports of the receiver. The experimental results of MUSIC-based DOA estimation show that C-USV approach is an accurate, effective and practical method for the MUSIC-based DOA estimation.
