Integrating New Bellhop Functionality into the Environmental Modelling Manager.

摘要

DRDC Atlantic has been developing a research-level acoustic prediction system in support of tactical decision aids and improving operator effectiveness: the System Test Bed (STB). Within the STB, the Environment Modeling Manager (EMM) is a client-server system that provides a human interface for an operator to request various types of Environmental Analysis (EA) -- such as transmission loss, signal excess, etc. The EA then manages behind-the-scenes calls to the Bellhop acoustic prediction engine, and when the results are ready, it displays them in the graphic formats selected by the operator. The EMM/EA is currently a passive-only system, predicting how sound would propagate from a distant vessel to a receiver. Recently, the Bellhop program has been enhanced to handle the performance modeling of active sonar operations. The subject of the present call-up is to upgrade the STB/EMM/EA with the most recent Bellhop program release and to enable the active-sonar analysis capability and towed-array receiver beam patterns.
