SimpleHydrophoneLocator

public SimpleHydrophoneLocator(PamArray pamArray,
 Streamer streamer)

Method Details

getPairSeparation

public double getPairSeparation(long timeMilliseconds,
 int phone1,
 int phone2)

Gets the angle between a pair of hydrophones in degrees in navigation units, i.e. clockwise from North

Parameters:

h1 - first hydrophone

h2 - second hydrophone

Returns:

angle from north in degrees

notifyModelChanged

public void notifyModelChanged(int changeType,
 boolean initComplete)

Specified by:

notifyModelChanged in class HydrophoneLocator

isStatic

public boolean isStatic()

Specified by:

isStatic in class HydrophoneLocator

Returns:

true if it's some sort of static array (not using GPS data in any way).

getArrayCenter

protected static double[] getArrayCenter(ArrayList<Hydrophone> hydrophones)

Find the origin point of the array. In the case of a paired towed array this will be halfway between the elements but in the case of more complicated towed array this will be the average positions of all the hydrophones

Parameters:

hydrophones -

Returns:

isChangeable

public boolean isChangeable()

Description copied from class: HydrophoneLocator

Note- changeable refers to the array positions changing relative to each other. i.e. the array doesn't change with heading or gps position, it's only changeable if the distances between hydrophones can change with time.

Specified by:

isChangeable in class HydrophoneLocator

Returns:

true if the hydrophone positions within the array can change with time
