The technology of hydrographic Side Scan Sonar has been developed by Professor Harold Edgerton and his colleagues in the year 1960. A Side Scan Sonar is a device that has the ability to search the space around it. The Sonar can be compared with a radar, but in a sonar the reflection of sound waves is used, unlike radar which uses electromagnetic pulses. Sound pulses usually range between 100 and 500 kHz. The frequencies higher than this magnitude have lower ranges, although they increase the accuracy and resolution.
