The Navy plans to do covert reconnaissance of minefields with a remote underwater vehicle that includes two sensors, one long-range (LR) and one short-range (SR). LR can detect mines, but it cannot distinguish them from harmless mine-like objects. SR can tell the difference, but only by approaching to within short range. A program called MIRES (Minefield Reconnaissance Simulator) is implemented to answer the questions of how the vehicle should perform a search and to estimate the number of mines remaining in the area once the reconnaissance is over. MIRES investigates four modes of search; a planned search with departure to identify an object, a planned search with no departure, and two kinds of random search. It compares these types of search and identifies the best search mode for a given scenario. http://archive.org/details/aminefieldreconn109455917 Civilian, Brazilian Navy Approved for public release; distribution is unlimited. |
