Abstract:

The HELSTAR program is analyzed with a view towards verification and validation. The program is divided into three major areas for parametric study battle management, laser system and battle scenario. The effects of atmospheric attenuation of laser energy, total number of attacking missiles, type of satellite orbit, and time-dependent launches on total system effectiveness are analyzed. In the course of the study, the effect of constellation altitude was found to have a significant effect on the size of the final optimum constellation. Since this altitude is determined by the program during initialization and cannot be controlled by the user, it can be considered to be a limitation of the program. Also, during the investigation of time-dependent launches, an error was found that led to invalid results. The exact location of this error could not be determined. Aside from the above mentioned limitations, the program was found to generate logical results. It was felt that potential users could use the program with a high degree of confidence that the engagements between ICBMs and space-based lasers were being modelled correctly. Author
