JRC JFE-680 User Manual

The echo of a seabed with abrupt slope is recorded as a lone difficult to see and less
discriminative, since it tends to accompany with a false echo due to the side lobe and the
inherent property of directivity.
In particular, a seabed with abrupt slope and heavily rugged surface provided an echo very
difficult to display on the recording.
