Alexandria, VA: Horizons Technology Inc. for Defense Nuclear Agency, 1988. Presumed First Edition, First printing [Version 1.0 stated]. Spiral bound. Very good. The format is approximately 6.25 inches by 8.5 inches. Various paginations (80 pages per Standard Form 298). Illustrations. Tables, Appendices. Cited References. RARE surviving copy. This was prepared for the Defense Nuclear Agency as part of their Electronic Handbook Series. The BLUEOUT program calculates the reverberant environment at a sonar receiver following an underwater nuclear detonation. I requires the following inputs: locations of the detonation and receiver; frequency of interest; ambient noise level of the ocean basin, amount below the ambient level a signal may fall and still be considered significant, number of interaction with the basin boundary to be calculated, and yield of the weapon. Output includes the amplitude, bearing, and start and end times of each signal that reaches the receiver, as well as the total signal level vs. time history. BLUEOUT can calculate the reverberant environment for the North Atlantic and North Pacific ocean basins. The models under by the BLUEOUT programs were developed by the Naval Surface Warfare Center and were originally implemented on a CYBER 720 mainframe computer in a program called REVERB. BLUEOUT is an adaptation of REVERB to run on an IBM PC or compatible computer.
