The Littoral Combat Ship (LCS) integrated bridge and combat scenario training systems for sailors replicates the layout and design of the LCS command and control, propulsion control systems, and bridge. However these simulators are incapable of displaying radar clutter such as rainstorms, sea surface scatter, land, trees, mountains, and buildings, nor other environmental effects. Clutter obscures targets of interest by overpowering their signal. An innovative software solution that models environmental effects into radar displays will increase the realism and effectiveness of training. IAI and its collaborators, John Hopkins University and Lockheed Martin, will design and develop the LCS Radar Modeling for Training (LRMT): a radar modeling engine capable of capturing the environmental effects, weather conditions, jamming and interference, and operator actions on radar displays. The purpose of this engine is to reduce and/or eliminate the need for live training by faithfully simulating the scenarios encountered by a radar operator.
