Abstract
The capability to detect object buried in the sea bottom is important both for the civilian society and for military purposes. For example, there are many places in the Baltic Sea where ammunition and poisonous gasses have been dumped. At FOI we are developing techniques for the detection of buried objects with sonar. This work is partly conducted in co-operation with other countries as part of the European MAST programme and the University of Lund. The scientific results from this work have been reported in papers and at conferences, but we have not given a description of our techniques. Therefore we present these in this report. We give a description of our underwater remotely operated vehicle, the PLUMS, together with a short description of sonar theory. We also give some examples from measurements on buried objects. In conclusion we give some recommendations on further work to be done in this research area.
