Abstract:

Vulnerability analysis programs, such as COVART, require target description data of sufficient detail and completeness to represent the physical and geometric detail of a target model from any attack aspect. The FASTGEN 3 computer model is used to generate the target description by developing a listing of the physical dimensions of target components, component location, and air spaces encountered along parallel shotlines passing through the target from a specified attack direction. A prerequisite to the execution of FASTGEN is the development of a geometric description of a target whose exterior and interior components surfaces are described using triangles, spheres, cones, cylinders, and rods. The objective of this manual is to provide a guide to experienced and inexperienced model developers to assist them in developing geometric models using the CONVERT computer code to generate target description data in the FASTGEN format. Specific model preparation procedures, recommended procedures, frequently encountered pitfalls and proven shortcut model preparation procedures are discussed. Emphasis is placed on the use of CONVERT constructs in model development. Vulnerability, Target recognition, Geometric target description, Geometric modeling.
