Figure 25. A sea floor and a single piling target with "good" settings
Figure 25, “A sea floor and a single piling target with "good" settings” shows a 3-dimensional image
generated from a single ping of a deep water bridge piling. The piling is clearly detected ahead of the vessel
at about 165 meters (545 feet) range. In this image, color is mapped to depth, and appropriate control
settings have been used. The control settings used to generate this image are shown at the top of the
screen shot. In this image, the Squelch is set to 170 dB. Let us now discuss how it was determined that
these are "good" settings.
