    Abstract: Buried objects detection topic has been explored and extended in order to detect underwater mines or other non-exploded ammunitions whether they are buried naturally or intentionally (riddens – sand dunes, mud).\nTowed magnetometers is currently the most used common method, in particular to clear Renewable Marine Energies areas, port extensions, and allow the installation and maintenance of submarine cable as well as wrecks searches. However the use of this equipment and the post-analysis data remain to be tedious and in some case not efficient. \nUnderwater cables are also a focus, it is therefore essential to detect and measure burial depth of cables.\nRTsys is currently developing an AUV prototype equipped with a side scan sonar and towed magnetic and acoustic detection antenna in order to meet the current market by improving existing technologies. This system is called BODAMM (Buried Objects Detection by Acoustics and Magnetics Methods).\nContrary to towed systems the use of an AUV allows to cover automatically a great area without requiring a specific ship and reducing the operator’s tiredness. The whole system can easily be deployed by only 2 people from a small boat.\nAlthough sonar and magnetic data processing methods are optimized (but still classic), the acoustic and sedimentary data exploitation uses SCAMPI® patented process which allows acoustic detection of buried objects.\nData acquisition occurs systematically when the AUV is making its programmed navigation. Data processing and merging are made in post mission. This data combined allow a high level distinction.\nAt last but not least the current system can be separated in two independent tools according to the operator’s needs: A « survey » AUV equipped with a side scan sonar and a towed magneto-acoustic array.\nBODAMM trials campaign are still going on and results obtained so far are very encouraging.
