Abstract

Direction of arrival is estimating for desire signal direction among received signal on antenna in spatial. In this paper, we were an estimation a receiving signal direction of arrival using multi beam forming in radar. We proposed, by signal direction of arrival estimation method, an algorithm which combine spatial correlation matrix weight value and beam steering algorithm in this paper. Through simulation, we were analysis a performance to compare general algorithm and proposal algorithm. In direction of arrival estimation, proposed algorithm is effectivity to decrease processing time because it is not doing an eigen decomposition. We showed that proposal algorithm improve more target estimation than general algorithm.

도래 방향 추정은 공간상에서 안테나에 수신된 원하는 신호의 입사 방향을 추정하는 것이다. 본 논문에서는 레이더에서 다중 빔 형성을 이용하여 신호 도래 방향을 추정하였다. 신호 도래 방향의 추정방법으로 본 논문에서는 빔 조향 제안 알고리즘과 공간 상관 행렬 가중치를 이용하였다. 모의실험을 통하여 본 연구에서 제안된 알고리즘 성능을 기존 알고리즘과 비교분석하였다. 목표물 도래방향 추정에서 본 연구에서 제안한 방법이 고유치 전개를 하지 않기 때문에 처리시간 단축에서 효과적이다. 본 연구에서 제안한 방법이 목표물 추정에서 기존 알고리즘보다 우수함을 나타내었다.
