순환정상성을 이용한 캐비테이션 초생 속도 분석기법 연구 = Study on Cavitation Inception Speed Analysis Methods using Cyclo-stationarity

다국어 초록 (Multilingual Abstract)

Cavitation inception speed (CIS) is a key factor of the acoustic stealth performance of naval ships because the level of underwater radiated noise begins to increase significantly after cavitation inception. Moreover, the acoustic feature could be provided to the enemy. The CIS is currently measured and managed by a strict naval procedure. Nevertheless, it is hard to measure and judge. Therefore, this paper suggests detection schemes of cavitation inception using the wide-sense cyclostationary process, which presents the noise characteristics of carriers and original tonal signals simultaneously. Then, the suggested scheme is verified to be more suitable for analysis of the CIS than existing schemes via a sea trial test.
