Abstract

This paper is estimating a target direction of arrival with incident to receiver in spatial. This paper presented covariance using constraint matrix to correlation interference signal cancellation in multi input multi output array antennas system. we proposed a target direction of arrival estimation algorithm using cost function and minimum variance method. Through simulation, we were analysis a performance to compare general SPT-LCMV algorithm and proposal algorithm. We showed that proposal algorithm improve more target estimation than general SPT-LCMV algorithm in direction of arrival.

본 연구는 공간상에서 수신기에 입사하는 목표물 도래방향을 추정하는 것이다. 본 연구는 다중 입력 다중 출력 배열 안테나 시스템에서 상관성 간섭신호를 제거하기 위해서 제한 행렬을 이용하여 공분산 벡터를 제시하였고 비용함수와 최소 분산방법을 이용하여 목표물 도래방향을 추정하는 알고리즘을 제안하였다. 모의실험을 통하여 본 연구에서 제안된 알고리즘 성능을 기존 SPT_LCMV알고리즘과 비교분석하였다. 목표물 도래방향 추정에서 본 연구에서 제안한 방법이 기존 SPT_LCMV알고리즘보다 우수함을 나타내었다.
