Conversion of the Vehicle Survivability Analysis Tool (VSAT) from Unix to Window
Abstract
Developed by Dynetics under an Anny contract, the Vehicle Survivability Analysis Tool (VSAT) predicts the detectibility of ground vehicles to smart weapons that use radar and infrared sensors. Vehicle designers use VSAT to specify signature levels required to defeat threat sensors. Dynetics wrote VSAT to run under the Unix operating system on Silicon Graphics computers, the prevalent platform for signature modeling in the mid 1990's. Currently, however, Microsoft Windows computers perform much of the modeling previously possible only on Unix machines. After a brief introduction to VSAT itself, this paper describes our conversion of the program into a Windows version for modem computers. Problems to be overcome in the conversion included changes in function names between the Unix and Windows programming languages,packaging of FORTRAN code and new techniques for handling variables. Moreover, a Windows GUI was created to interface with the user. After the conversion, test cases run on the converted program verified that the Windows and Unix versions produced identical results.
