Near-field Source Localization Method using Matrix Pencil

Abstract

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. 예측 기법(linear prediction), [5] higher-order ESPRIT, [6] cumulant 기반 [7] 등의 기법이 제안되었지만 추가적으로 II. 신호 모델
