User's Manual for the Screen Program.
Abstract
This report explains how to use the SCREEN program, a computer program designed to evaluate acoustic detection and localization performance of an antisubmarine protective force about a Naval task force or other shipping. A companion report documenting the theory of the SCREEN program supplements this report. The measures used to evaluate the SCREEN performance are: cumulative detection probability against specific target approach tracks and cumulative localization performance against these same tracks. In addition to cumulative measures, 'snapshot' detection and localization measures are also computed, which provide an indication of the detection and localization coverage of the defensive screen at a specified time. The SCREEN program operates on data files which contain moderately detailed descriptions of the acoustic environment (propagation, noise, etc.), the sensor parameters and tactics, and the screen penetrator (target) parameters and tactics. These descriptions include both deterministic and stochastic parameters. The data files contents can be created, altered, and displayed by the user under program control. Once the data files have been created, subsequent use of SCREEN is straightforward and concise, involving user-selectable program options and machine prompts for input. Bayesian updating techniques are used to evaluate search effort, along lines similar to techniques found in computer assisted search programs which are currently being implemented in the Fleet.
