Abstract

In recent years, with the advance in analytical and calculating ability of scientific spreadsheets and the increasing speed of PC machines, it is now possible for any sensor system designer to carry out basic performance analysis without always having to refer to special purpose performance models. The designer can use these spreadsheets to custom-make any system and subsystem models for his own purpose. The spreadsheet models presented in this paper will demonstrate the analysis of horizontal and vertical 4- bar target responses of a serial scan FLIR system by using a commercially available scientific spreadsheet (i.e., MathCAD version 4.0). The results from the model have shown excellent correlation with actual measured data. Finally, this ability to accurately predict subsystem performances have proven to be extremely useful not only during the design phase, but also during the prototyping and preproduction integration phase. Because during trouble-shooting efforts, it provides the engineers the ability to understand subsystem problems in an almost real time fashion.
