Abstract

In this paper, we propose a broadband beamforming method using the Spatial Response Variation (SRV) which is defined to measure the fluctuation of the array spatial response within the desired frequency band. By applying the SRV to regularization term, we achieve a good quality main beam width variation less than 1 degree within the desired frequency band. In design experiments, we show that the proposed method is better than the existing method.

본 논문은 공간 응답 변화량(Spatial Response Variation, SRV)을 사용한 광대역 빔 형성 방법을 제안한다. SRV를 정규화 항으로 적용하여 목표하는 주파수 대역에서 주 빔 폭의 변동이 약 1도 이내로 적은 양질의 광대역 빔패턴을 얻도록 하였다. 설계 실험에서 제안 된 방법이 기존 방법보다 낫다는 것을 입증하였다.
