Observation of the underwater area is the element of general trend which primary purpose is to protect and enhance the safety of the selected region. The aim of the paper is to present the acoustic characteristics of typical objects floating on the surface or under the water, which constitute some knowledge on how to detect these objects. Create a catalog of acoustic signatures and acoustic images of objects mostly floating under water can be an important contribution to the efforts to increase the safety of water areas and located in the vicinity of the nearby public objects. This is part of the overall security policy with respect primarily to the type of terrorist threats and sabotage but not only. During research passive detection acoustic methods (linear hydrophone array) and active like side scan sonar where use with an emphasis on pontoon with engine and diver with air cylinders tried to pass through the protected area. Results of detection will be presented and discussed.
