Sidescan sonar

Sidescan sonar

A survey method used in underwater archaeology which provides the broadest view of the sea-floor. An acoustic emitter is towed behind a vessel and sends out sound waves in a fan-shaped beam. These pulses of sonic energy are reflected back to a transducer-- return time depending on distance traveled--and recorded on a rotating drum.
