Method Detail

setLocations

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

Set the locations of hydrophone and the source

Parameters:

hydrophoneLatLong -

hydrophoneDepth -

sourceLatLong -

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

getNumPaths

int getNumPaths()

Get the number of propagation paths that will be returned

Returns:

number of paths

getDelays

double[] getDelays()

Get the time delays for each path

Returns:

delays in seconds

getPointingVectors

PamVector[] getPointingVectors()

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

Returns:

Vector pointing from source to receiver.

getGains

double[] getGains()

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

Returns:

path gains.

getName

java.lang.String getName()

Returns:

name
