Abstract

멀티 빔 음향시스템이 개시된다. 상기 멀티 빔 음향시스템은 마이크 어레이로부터 입력되는 입력신호를 원하는 방향으로 조향(steering)하는 고정 빔 형성부, 상기 입력신호를 수신하고 수신된 상기 입력신호로부터 잡음 기준 신호를 획득하기 위한 블록킹 행렬부(blocking matrix), 상기 블록킹 행렬부로부터 출력되는 상기 잡음 기준 신호로부터 적응형 잡음 신호를 획득하기 위한 가변 빔 형성부, 및 상기 고정 빔 형성부로부터 출력된 신호에서 상기 적응형 잡음 신호를 제거한 목적신호를 출력하기 위한 제거수단을 포함하는 GSC(Generald sidelobe Canceller)를 포함하는 특징으로 하며, 상기 고정 빔 형성부는 적어도 두 개의 방향으로 상기 입력신호를 조향하는 것을 특징으로 할 수 있다.
