Abstract
High-frequency bistatic sediment scattering experiment was conducted in the shallow waters off the east coasts of Korea. Acoustic data were taken as a function of grazing angle(30, 45, and 60 deg.), scattered angle(30, 45, and 60 deg.), and bistatic(azimuthal) angle(0, 60, and 120 deg.). Besides a flat bottom it was artificially raked so as to produce directional ripples. The measured scattering strengths for Jackson et al.. The surface reverberation component is seen to dominate over the volume scattering part at the frequency of 240 kHz. Compared to the flat bottom case, the scattering strengths for directional ripples showed lower and higher variation depending on the ripple's orientation.
