Abstract

In this paper, near-field source localization algorithm is presented using Matrix Pencil in Uniform Linear Array(ULA). Based on the centrosymmetry of the ULA, the proposed algorithm decouples the steering vectors which allow for the bearing estimation using Matrix pencil. With estimated bearing, the range estimation of each source is consequently obtained by defining 1D MUSIC spectrum. Simulation results are presented to validate the performance of the proposed algorithm.

본 논문은 선형 선배열에서 Matrix Pencil(MP) 기법을 이용해 별도의 탐색과정 없이 근거리 음원의 방위를 추정하는 기법을 제안한다. 제안한 기법은 선형 선배열에서 근거리 음원이 가지는 대칭성을 이용하여 조향 벡터를 거리 독립적인 항으로 변화 시킨 후 MP 기법을 적용한다. 각 음원의 거리는 앞서 추정된 방위 정보를 이용하여 음원 수만큼의 1차원 MUSIC 기법을 적용하여 추정된다. 제안된 알고리즘은 시뮬레이션을 통해 성능 검증을 하였다.
