dc.description.abstract해수면 상태에 따른 고주파 양상태 해수면 음파산란 채널 측정 실험은 2020년 4월 거제 내만해역에서 수행되었으며 산란이론을 기반으로 한 모의결과와 비교하였다. 신호는 중심주파수 128 kHz, 대역폭 32 kHz의 선형 주파수변조 신호를 이용하였다. 파고부이를 통해 측정된 해수면 거칠기로부터 해수면 파수 스펙트럼을 계산하였고 산란이론인 Small Slope Approximation(SSA)에 적용하여 해수면 거칠기에 의한 산란강도를 추정하였다. 또한 실험 당시 풍속을 이용하여 해수면 부근 공기방울층 음파산란을 고려하여 산란강도를 계산하였다. 모의된 산란강도를 이용하여 해수면 산란 채널 세기 임펄스 응답을 모의하였고, 해수면 파수 스펙트럼과 공기방울층 산란에 따른 모의결과를 측정 치와 비교, 분석하였다.-
