The use of Autonomous Underwater Vehicles (AUVs) for the detection of buried mines offers the advantages of lower cost, stealth, and potentially improved coverage rates over more traditional mine hunters. However, in the case of bistatic detection scenarios, AUVs have difficulty knowing where exactly they are in space and the trigger time of sources on other platforms. In this paper the problems of inaccurate navigation and source timing information are addressed. In an experiment conducted off Marciana Marina, a MIT AUV with a SACLANTCEN nose array and acquisition system was used together with a TOPAS parametric sonar to explore issues of buried target detection using AUVs.
