reflect_loss_model Class Reference
[Ocean Boundaries]


Detailed Description

A reflection loss model computes the changes in intensity and phase that result from the reflection of a ray from a boundary.

Reflection is calculated on a ray-by-ray basis instead of across the wavefront because only selected rays interact with the boundary at any given time step. These models compute their results as a function of frequency to support broadband acoustics.


Constructor & Destructor Documentation

virtual ~reflect_loss_model (  )  [inline, virtual]

Virtual destructor.


Member Function Documentation

virtual void reflect_loss ( const wposition1 location,
const seq_vector frequencies,
double  angle,
vector< double > *  amplitude,
vector< double > *  phase = NULL 
) [pure virtual]

Computes the broadband reflection loss and phase change for a single location.

Parameters:
location Location at which to compute reflection loss.
frequencies Frequencies over which to compute loss. (Hz)
angle Grazing angle relative to the interface (radians).
amplitude Change in ray intensity in dB (output).
phase Change in ray phase in radians (output). Phase change not computed if this is NULL.

Implemented in boundary_model, reflect_loss_beckmann, reflect_loss_constant, reflect_loss_eckart, reflect_loss_netcdf, reflect_loss_rayleigh, and reflect_loss_rayleigh_grid.
