Range-Dependent Ocean Acoustic Transmission Loss Calculations in a Real-Time Framework,

Abstract

Most anti-submarine warfare (ASW) trainers for either airborn or seaborne platforms require the simulation of ocean acoustic transmission loss to model the submarine signals received by sonobuoys or towed/hull arrays. With operational fleet equipment gaining in sophistication, the ocean acoustic software which stimulates this equipment must be refined. The introduction of range-dependent transmission loss calculation is one of the most important refinements. However, the associated theoretical problems are complex, and their solutions are difficult to implement practically, especially in simulators that require real-time software. This paper discusses some of the complications that range-dependent ocean acoustic modeling introduces and uses a prototype model, the Multiple-Profile Configuration (MPC) Ocean Model, developed by the Link Simulation Systems Division of the Singer Company, to present specific methods of resolving these complications.
