Abstract

In this paper, we studied for modified bartlett method to estimate desired information signal. Constrained length of bartlett method is assigned as one, and estimate desired information signal to compensate for delay time. Modified bartlett method is an optimum direction-of-arrival (DoA) estimation algorithm to apply delay time compensation to update optimum weight. The optimum weight is used linear constrained minimum variance method(LCMV). Through simulation, we are comparative analysis proposed algorithm and general Bartlett and MUSIC method. In desired signal estimation, condition simulation is an array antenna element numbers 6 or 9 and desired information signals number 3. We show the superior performance of the proposed algorithm relative to the existing method in estimation of desired information signal.

본 논문에서는 원하는 정보 신호를 추정하기 위해서 수정 Bartlett방법에 대해서 연구하였다. Bartlett방법은 구속 장을 1로 설정하고, 시간지연을 보상하여 원하는 정보 신호를 추정하는 방법이다. 수정 Bartlett방법은 최적 가중치 갱신치를 지연시간 보상에 적용하여 최적의 도래방향 신호를 추정하는 방법이다. 최적가중치는 선형구속최소분산 방법을 사용하였다. 모의실험을 이용하여 본 연구에서 제안한 방법과 기존 Bartlett 과 MUSIC방법의 성능을 비교 분석한다. 모의실험조건은 배열 안테나 소자 수 6개와 9개, 원하는 정보신호 3개[-15o, 0o, 15o]에서 원하는 신호를 추정한다. 원하는 정보 신호 추정에서 본 연구에서 제안한 방법이 기존의 Bartlett 과 MUSIC방법보다 분해능이 우수함을 입증하였다.
