Olson Stuart, Williams Robert. Methodology for computer-generation of lines of constant burst-kill probabilities (Footprints) for gun air defense systems (ISO-PK)

Army Armament Command, Rock Island, IL, Systems Analysis Directorate, 1976. — 99 p.An important tool for analyzing the relative effectiveness of gun air defense systems is a plot of lines of constant (ISO) probability of kill (PK) in the volume of space surrounding the planned deployment of the system; hence, the name ISO-PK. These plots are usually presented as two-dimensional sections taken at selected places in the volume. The lines of constant kill probability sometimes form eliptical traces and, perhaps, for this reason, they are commonly referred to as 'footprints'. This report presents the computer program and explains the algorithm which calculates the burst-kill probability and automatically plots the footprints on a computer line printer. Also included in this report is an analysis of weapon pointing errors which includes the effects of lead angle generation. This model, which may be termed an error budget model, was originally developed for the Air Defense Evaluation Board (ADEB). Instructions for use of the program and a sample problem are presented.
