Abstract
The SWAMI (Shallow Water Active-sonar Modelling Initiative) toolset in use at DRDC Atlantic contains modules to produce predictions of transmission loss, reverberation, signal excess, and probability of detection. The toolset includes a capability to consider many source and receiver configurations from omnidirectional to line-arrays (horizontal and vertical) to volumetric arrays. The environment can vary both azimuthally and radially (Nx2D). This paper presents measurements made through a Joint Research Project with the NATO Undersea Research Centre called BASE 04 (Broadband Active Sonar Enhancement 2004). The towed-array reverberation data and associated model predictions using the SWAMI reverberation model are presented.
