dc.description.abstract | 천해에서 포물선 근사 (parabolic approximation)에 기초한 저주파 양상태 잔향음 모델 (LHYREV-B, Low-frequency Hanyang Univ. Reverberation model-Bistatic)을 제안하였다. LHYREV-B 모델에서는 해저와 해저지형 내의 상호작용을 포함하는 음향모델에 수평입사에 독립인 산란함수를 이용하여 양상태 잔향음을 계산하였다. 모델의 검증을 위하여 실측 잔향음 신호와 비교하였으며, 비교 결과 LHYREV-B 모델이 저주파 잔향음 예측에 적합함을 확인할 수 있다. Low-frequency hi-static reverberation model (LHYREV-B, Low-frequency Hanyang univ. Reverberation model-Bistatic) based on the parabolic approximation for shallow water environment is presented. In this paper bistatic reverberation level is computed using the angle-independent scattering strength function and the wave-based acoustic model. The signal simulated by the LHYREV-B model is compared with the observed signals and it is shown that the LHYREV-B model provides a closer fit to the observed signals. | en_US |
