Abstract

The performance of anti-submarine sonar detection is required to improve by the development of submarine noise reduction technology. because of the need of an anti-submarine detection ability, known for superior beamforming performance, adaptive beamforming algorithms have been considered as an alternative beamforming algorithm of a conventional beamforming algorithm. In order to achieve improved performance by applying an adaptive beamforming algorithm to the sonar system, the adaptive beamforming algorithm applicability of system must be verified, To do this, the performance index for the system applicability must be established. In this paper, a tracking initiation probability of the adaptive beamforming algorithm and the conventional beamforming algorithm was calculated and the performance of both techniques was quantified, a system applicability of the adaptive beamforming algorithm was reviewed.

잠수함 정숙화 기술의 발달로 대잠 소나의 탐지성능 향상이 요구되고 있다. 이와 같은 성능향상의 필요성에 의해 소나체계에 널리 쓰이는 일반적인 빔형성 기법(CBF : Conventional BeamForming)보다 성능이 뛰어난 적응 빔형성(ABF : Adaptive BeamForming) 기법이 대체 알고리즘으로 검토되고 있다. 소나 체계에 적응 빔형성기를 적용하여 성능향상을 도모하기 위해서는 적응 빔형성 기법의 체계 적용성이 검증되어야 하는데 이를 위해서는 체계 적용성을 측정하기 위한 성능지표가 정립되어야 한다. 본 논문에서는 적응 빔형성기와 일반적인 빔형성기의 추적 개시(Tracking initiation) 확률을 산출하여 두 기법의 성능을 정량화하여 적응 빔형성기의 체계 적용성을 검토하였다.
