근접장에서 가상 합성 배열을 이용한 수중 이동체의 토널 소음 측정 방법 = A method for measuring tonal noise of underwater vehicle using virtual synthetic array in near-field

다국어 초록 (Multilingual Abstract)

A receiving array system can be applied for tonal noise analysis of underwater vehicles, but it is difficult to install and operate, and a lot of cost is required. In order to overcome this problem, this paper proposes a method to measure the tonal noise of underwater vehicle after synthesizing a virtual array using single receiver. The proposed method compensates the Doppler frequency and time delay caused by the movement of the underwater sound source and applies the focused beamforming technique. The performance of the proposed method was analyzed via simulation.
