| dc.description.abstract | 소나 체계에서 은밀성을 유지한 채 표적의 거리를 추정하는 것은 중요한 문제이다. 본 논문에서는 배열 불변성 기법을 통해 수평 선배열에서 음원의 거리를 추정하였다. 이 기법은 환경 정보가 불필요하며 연산량이 적어 실시간 거리 추정이 가능하다는 장점을 가지고 있다. 알고리듬을 검증하기 위해 해상실험 데이터에 기법을 적용하고 모의실험 결과와 비교하였다. 그리고 음원의 방위각, 송신 신호의 길이, 수신기의 설계주파수와 길이에 따른 거리 추정 성능을 모의실험을 통해 보이고 이를 분석하였다. | - |
