도달각(AOA)을 추정하기 위해 안정된 위상 중심을 갖는 균일 선형 배열(ULA)로 구성된 기준선을 사용하는 위상 간섭계는 항상 방향 찾기(DF) 시스템에 사용됩니다. 그러나 안테나 요소의 위상 중심은 입사각, 주파수, 다중 경로 등에 따라 달라질 수 있습니다. 이러한 문제를 해결하기 위해 본 논문에서는 초광대역(UWB)에서 위상 중심을 교정하는 새로운 방법을 제안합니다. 한편, 이 방법의 제한 사항에 대해 논의합니다. 수치 시뮬레이션은 제안된 방법으로 더 높은 정확도와 더 큰 명확한 각도 범위를 얻을 수 있음을 보여줍니다.

Abstract: Phase interferometer using baseline composed by uniform linear array (ULA) with stable phase center for estimating the angle of arrival (AOA) is always employed in the direction finding (DF) system. However, the phase center of antenna element could vary with the incident angle, frequency, multipath and so on. To deal with these problems, a novel method is proposed in this paper to calibrate the phase center over ultra-wideband (UWB). Meanwhile, the restrictions of this method are discussed. Numerical simulations reveal that higher accuracy and larger unambiguous angle range can be obtained by the proposed method.
