Sonar measurements in the process of bottom mapping are performed to obtain an image that confirms the presence of an object or objects under water.
The realized measurements allow to determine their location, shape and dimensions. Indicating the values of direction and distance between the sonar transducer and the object, which rests on the tank bottom, results in obtaining sonar image information.
BOTTOM MAPPING IN SONAR SURVEYS
Sonar surveys can distinguish underwater objects close together as single echoes on a sonogram. UXO Marine performs sonar surveys with state-of-the-art equipment that uses sound waves to navigate, detect and classify objects:
SSS SIDE SONAR
Towfish side scan sonar (SSS) system for imaging the substrate of a body of water to obtain information on bottom morphology and to size objects (either on the surface or partially buried in it). The side scan sonar can be attached to the side or towed behind the vessel.
SLS FRONT SONAR
FLS (forward looking sonar) system for dual-frequency, high-quality multibeam imaging used when mounted on an inspection-grade ROV or on a diver's mask or helmet.
Sonars, during the inspection of water reservoirs, allow to obtain the image of the bottom surface even in several hundred meters long stripes and thus distinguish types of bottom sediments or forms formed of them.
