Abstract

In this paper, we are comparative analysis of exit algorithm and proposal algorithm for desired target direction of arrival estimation in correlation signal system. Proposed algorithm in this paper is to decrease target direction of arrival an estimation error probability using bayesian, maximum posterior, and MUSIC algorithm in order to decrease direction of arrival error probability as optimize and use linear constrained minimum variance to update weight value. Through simulation, we were comparative analysis proposed algorithm and exit MUSIC algorithm. In case SNR is 10dB and antenna element arrays are 9 and 12, We show the superior performance of the proposed method relative to the class method to decrease of signal estimation error probability about 11% and 13%, respectively.

본 논문에서는 상관성 신호 시스템에서 원하는 목표물의 도래방향을 추정하기 위한 기존 MUSIC알고리즘과 제안 알고리즘에 대한 성능을 비교 분석한다. 본 논문에서 제안한 알고리즘은 가중치 갱신을 위해서 선형 구속 최소 분산 방법과 도래 방향 오차 확률을 최적으로 감소시키기 위해서 베이스 방법과 최대 사후 확률에 MUSIC알고리즘 적용하여 목표물 도래 방향 추정 오차 확률을 감소하고자 한다. 모의실험을 이용하여 본 연구에서 제안한 알고리즘과 기존의 MUSIC알고리즘의 성능을 비교 분석하였다. 신호대 잡음비가 10dB이고 안테나 배열 개수가 9개와 12일 때, 본 논문에서 제안한 알고리즘이 기존의 MUSIC알고리즘보다 각각 약 11%와 13%의 도래 방향 추정 오차를 감소시켜 본 연구에서 제안한 알고리즘이 우수함을 확인하였다.
