Towed Array Performance Prediction System - Version 1.2.

Abstract

Several software enhancements to the Towed Array Performance Prediction System (TAPPS) are described. A technical discussion of the changes is given, and the implementation and testing of the software modifications on the Nova 820 computer are documented. The latest software is denoted as TAPPS version 1.2. An interim improved treatment of bottom loss, denoted as interim Bottom-Loss Upgrade (BLUG) is discussed. A set of six new bottom-loss classes and associated bottom-loss curves for the Indian Ocean, and new bottom-loss curves in the other ocean areas are presented. These changes have been fully integrated with the TAPPS propagation-loss model (FACT), as well as the TAPPS noise Model. A new surface-duct propagation-loss model is a refinement and extension of Labianca's virtual mode results. The results of Spofford and Ryan had previously been used to develop a replacement model for the Clay Surface- Duct Model within FACT. The implementation of these results in TAPPS are discussed.
