dc.description.abstract | 소나 탐지확률을 계산하는 경우, 수중음향 불확정성은 표준편차가 8 dB ~ 9 dB인 정규분포를 따르는 것으로고려되고 있다. 하지만, 소나 탐지성능은 실험해역, 해양환경 변동성에 따라 크게 변화하기 때문에 해상실험 데이터기반의 수중음향 불확정성을 반영한 탐지성능 예측이 필요하다. 본 논문에서는 동해 천해환경에서 측정된 중주파수(2.3 kHz, 3 kHz) 소음준위와 전달손실 자료 기반의 수중음향 불확정성이 산출되었다. 해상실험 데이터 기반의 수중음향 불확정성을 반영한 예상탐지확률을 산출한 후, 이를 기존의 탐지확률 결과, 레일리 분포의 불확정성과 음으로 치우친 분포의 불확정성을 반영한 예상탐지확률 결과와 비교하였다. 결과적으로 각각의 수중음향 불확정성에 따라 탐지영역의 차이가 발생하는 것을 확인할 수 있었다. | - |
dc.description.abstract | When calculating sonar detection probability, underwater acoustic uncertainty is assumed to be normal distributed with a standard deviation of 8 dB to 9 dB. However, due to the variability in experimental areas and ocean environmental conditions, predicting detection performance requires accounting for underwater acoustic uncertainty based on ocean experimental data. In this study, underwater acoustic uncertainty was determined using measured mid-frequency (2.3 kHz, 3 kHz) noise level and transmission loss data collected in the shallow water of the East Sea. After calculating the predictable probability of detection reflecting underwater acoustic uncertainty based on ocean experimental data, we compared it with the conventional detection probability results, as well as the predictable probability of detection results considering the uncertainty of the Rayleigh distribution and a negatively skewed distribution. As a result, we confirmed that differences in the detection area occur depending on each underwater acoustic uncertainty. | - |
