Side Scan Sonar
Home> Products> Side Scan Sonar
Side Scan Sonar is a sonar system that is used to efficiently create an image of large areas of the sea floor, or riverbed. SonarBeam provides two kinds of side scan sonar, one is S-150 series by single beam(dual frequency), and another is 400 series by multi-beam (3, or 5 beams) |
