Abstract:

Target vulnerability assessment requires accurate information about physical target parameters. This information allows the analyst to draw experimental conclusions or model phenomena which are deemed predictable. At the Ballistic Research Laboratory BRL, computerized descriptions capture the geometry of the physical target and are constructed using the Multi-device Graphics Editor MGED, allowing interactive manipulation of solid geometric primitives and their boolean combinations. This approach, using Constructive Solid Geometry CSG, allows the analyst to create shapes and refinements to the accumulated geometric data to fulfill the requirements for a wide range of analysis tasks. Geometry created using MGED can be interrogated using many of the tools incorporated in BRL-CAD software package. This handbook prepares novice analysts to appropriately address a number of geometric description problems. Details of the MGED editor are explained, manipulation of the primitives is explored with reproducible examples provided, and description database organization issues are addressed. A fully integrated approach to target description for use in vulnerability analyses is presented in a prescriptive format to facilitate any analysis task.
