STARFISH SIDE SCAN IMAGERY
Understanding and interpreting side scan sonar imagery may seem difficult at first, but with practice and some knowledge of how the sonar works, it doesn't take very long for an operator to understand what the seafloor is doing below the sonar, and if there are any targets on it.
Many people try to look at the pictures and understand them as you would a photograph, but this however is not strictly the case. In the following sections, we will look at several example images, and see how information can be obtained from them.
