Abstract: Loss of Function (LoF) values can be precalculated for a given target/threat combination using the U.S. Army Research Laboratory's Survivability/Lethality Analysis Directorate's Modular, Unix-based Vulnerability Estimation Suite (MUVES-S2). In order to minimize file sizes, tabulated LoF values are commonly referenced to target-centered coordinates. However, weapon-effectiveness models and combat simulations typically use generalized battlefield coordinates. Presented in this report is a method for determining LoF values that are referenced to battlefield coordinates. The method uses multiple, target-centered, LoF data sets, where target/threat orientations are varied across data sets. Inherent in this method is a procedure for interpolating between discrete data points in three dimensions, one of which is periodic. Finally, a C++ implementation of the method is included as an appendix. The C++ code has been designed to be embedded into larger weapons-effectiveness models and combat simulations, thus improving their ability to analyze vehicle targets.
