New Capabilities for Side-Scan Sonar

Abstract

Now that side-scan sonar has become a generally accepted remote sensing tool, technical developments are proceeding at a rapid pace. Until recently, basic systems primarily used straightforward analog signal processing, and digital techniques were confined to recorder functions such as stepping motor drivers. Now manufacturers are adapting methods to use more sophisticated analog and digital techniques to improve the quality of the sonar images. Continuing improvements are also seen in graphic recorders, transducers, and towing vehicles.
