SphericalPropagation

public SphericalPropagation()

Method Detail

getDelays

public double[] getDelays()

Description copied from interface: PropagationModel

Get the time delays for each path

Specified by:

getDelays in interface PropagationModel

Returns:

delays in seconds

getGains

public double[] getGains()

Description copied from interface: PropagationModel

Get the gains for each path

These are the inverse of attenuation and are a scale factors NOT in dB so that surface reflections can be given a negative number

Specified by:

getGains in interface PropagationModel

Returns:

path gains.

getNumPaths

public int getNumPaths()

Description copied from interface: PropagationModel

Get the number of propagation paths that will be returned

Specified by:

getNumPaths in interface PropagationModel

Returns:

number of paths

setLocations

public boolean setLocations(LatLong hydrophoneLatLong,
                   double hydrophoneHeight,
                   LatLong sourceLatLong,
                   double sourceHeight,
                   double speedOfSound)

Description copied from interface: PropagationModel

Set the locations of hydrophone and the source

Specified by:

setLocations in interface PropagationModel

sourceHeight - - i.e. normally this will be negative within the code even though the dialog may show a positive number for depth !

Returns:

true if model ran OK

getName

public java.lang.String getName()

Specified by:

getName in interface PropagationModel

Returns:

name

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getPointingVectors

public PamVector[] getPointingVectors()

Description copied from interface: PropagationModel

Get a list of vectors pointing from the sound source to the receiver (or it's apparent location for surface echos).

Specified by:

getPointingVectors in interface PropagationModel

Returns:

Vector pointing from source to receiver.
