Abstract: A feeder program is utilized for collecting and reading in and maintaining a time synchronization for combat fire solutions which may include threat containment regions. The threat containment regions are defined in terms of a probability of at least one threat being located therein. A three-dimensional viewer program displays bathometry information, an ownship relative position relative to said bathometry information, and determines what portions of said plurality of threat containment regions and said tracking and position information are to be displayed based on an angle of a view.

Abstract: Disclosed is a method for extracting and rendering data from digital charting databases. The software method integrates and combines bathymetric/topographic data from several sources into a stream of three-dimensional data points, creating a triangle surface mesh, and dividing it into pieces along arbitrary lines to create regularly sized and shaped areas for efficient storing and rendering. The method works by forming an initial triangle mesh of the area and then refining the mesh by incrementally adding each point to the mesh, until a full mesh representation is achieved. The large single file is then broken down into discrete geographic regions, and the region data is converted into a standard file format for viewing and/or processing.

Abstract: A three-dimensional imaging system for use with a sonar system. The three-dimensional imaging system processes forward-looking sonar data, side-looking sonar data, bathymetric data, detection and cluster data, bottom sediment type data, and vehicle position and navigation data and renders a complete three-dimensional image of an ensonified region.

Abstract: An underwater testing platform assembly includes first and second rails for disposition in part in a body of water, each of the rails having facility for connection to a surface vessel. The rails are disposed vertically, parallel to each other. A cage comprising a network of struts is mounted on the rails. A skid is mounted on, and is movable in, the cage, and can receive and retain an apparatus to be tested. First and second travelers are fixed to the cage and are movably mounted, respectively, on the rails, such that the cage is vertically movable on the rails. Instrumentation is mounted on the cage. A transmission line is connected at a first end to the instrumentation and extends to the surface vessel. A receiver on the surface vessel has a second end of the transmission line connected thereto and receives data signals from the instrumentation.
