Abstract
- Ambient noise is a principal factor degrading the signal-to-noise ratio (SNR) of sonar systems. In shallowwater waveguide, it is greatly influenced by waveguide properties such as sea surface condition, geoacousticproperties of the bottom and sound speed profile in water medium [1]. The snapping shrimp, which is widelydistributed throughout all coastal area of Korea, is a dominant noise source in the ambient noise. The frequencybandwidth of a shrimp snapping noise is very wide compared to those of other biological sources. The upperfrequency limit of the snapping sound extends to 250 kHz [2]. After the snapping sound is generated by thesnapping shrimp, it transmits though the ocean waveguide and thus it is influenced by interactions with the seasurface and seabed boundaries, which motivates this study.om and sound speed profile in water medium [1].
