SEARCH and EVIDENCE RECOVERY

DIDSON™ can be used to help recover lost or discarded objects as well as examine underwater structures. If the search area is small, DIDSON can be used both for the initial search (low frequency mode) and the final identification and recovery (high frequency mode). If the search area is large, it is first covered with the side-scan sonar. The side-scan sonar generates a map with bright marks that indicate where there are large acoustic returns. The operators prioritize the marks, go to the locations, and send down an ROV, AUV, or a diver with a DIDSON to identify if it is a false target or the object of interest.
