KWEval

KWEval (Kinetic Warhead Evaluation) is a fast running terminal endgame code that predicts damage induced to a Ballistic Missile payload from interaction with a Kinetic Energy Weapon (KEW). Damage predictions are compared to lethality criteria for the weapon system (or family of weapon systems) to generate output quantifying whether the payload or payload components were destroyed beyond a threshold value. KWEval runs on a personal computer platform. Valid host operating systems are Windows family (95,98,NT, 2000,and DOS).

The main processor that handles information flow into modular routines is written in C++. This language provides a valuable control mechanism for implementation of new algorithms. Modular routines can be written in either C++ or Fortran provided that those routines comply with interfacing specifications. If Fortran routines are developed, those routines are converted into a Dynamic Link Library (DLL) and accessed by the main processor via subroutine calls.

Code execution is performed via command-line at DOS prompt or in MS Windows by clicking on the KWEVAL.exe file name. Future versions of KWEval will have a Graphical User Interface (GUI) to assist both problem setup and output post-processing. Prior to code execution, all input files required to successfully complete a run, or series of runs, must be accessible to the code. These include KWEVAL.DAT, OPARAM.DAT, ‘interceptor file(s)’, ‘target file(s)’, and ‘engagement file(s)’. File format detail is illustrated and documented in the KWEval Users Manual. Additional detail about KWEval and supporting analysis tools can be found in a Final Report, titled “Research in Target Vulnerability and Weapons Lethality”.
