Description

Class Summary

Beam	A Beam is defined as the volume swept out by four Rays as they traverse the ocean environment.
Bottom	Simulates the acoustic characteristics of reflection, absorption and geometry for the ocean bottom.
ExampleBeamDynamic	Produces an example VRML 3D scene ExampleBeamDynamic.wrl showing a Beam.
ExampleBeamStatic	Produces an example VRML 3D scene ExampleBeamStatic.wrl showing a Beam.
ExampleColorBar	Produces an example VRML scene displaying a colorbar.
ExampleLobeDynamic	Produces an example VRML 3D scene ExampleLobeDynamic.wrl showing a Beam.
ExampleLobeStatic	Produces an example VRML 3D scene ExampleLobeStatic.wrl showing a Lobe, and also includes several sonar visualization examples.
ExampleRay	Produces an example VRML 3D scene ExampleRay.wrl showing a Ray.
Lobe	A Lobe is defined by combining multiple Beams, which in turn are made up of Rays.
NormalMode	This class provides methods useful to Normal Mode calculations.
PrintVRML	Utility methods used to build a VRML scene, each returning standard VRML node strings.
Ray	Ray implements the Recursive Ray Acoustics (rra) Algorithm derived by Professor Lawrence Ziomek to rapidly calculate a sound ray's 3D path through water, taking into account piecewise-local SSP, Surface and Bottom conditions.
SSP	Sound Speed Profile (SSP) describes the acoustic characteristics of refraction for the local volume of water which the Ray is passing through.
Surface	Simulates the acoustical reflection and absorption characteristics of the ocean's surface.
Targets	This class provides methods for random target generation, tracking updates to the dead-reckoned positions of targets, and detecting whether a sonar ping has collided with any of the Targets.
TransmissionLoss	This standalone application tests the energy transport accuracy of the rra algorithm.
TransmissionLoss2d	This standalone application tests the energy transport accuracy of the rra algorithm.
TransmissionLossNormalMode	This standalone application generates transmission loss data using normal mode calculations, which is the energy transport standard to which rra is compared.
Vec3d	Vector arithmetic routines for 3-element vectors of type Double.
