Interface HydrophoneLocator

All Known Implementing Classes:

SimpleHydrophoneLocator, StaticHydrophoneLocator, StraightHydrophoneLocator, TerrellaHydrophoneLocator, ThreadingHydrophoneLocator

public interface HydrophoneLocator

HydrophoneLocator is an interface for objects that can work out the true positions of hydrophones based on any or all of the following information

The set positions for each hydrophone from the array dialog

The movement of the vessel (e.g. the hydrophone may thread behind the vessel

Any sensor information available, e.g. depth, Terella, etc.

Method Detail

getReferenceLatLong

LatLong getReferenceLatLong(long timeMilliseconds)

Gets a reference LatLong for the locator at a given time. For towed hydrophones, this will be the ships gps position at that moment. FOr static phones it will be the static array reference position.

Parameters:

timeMilliseconds - time reference needed for

Returns:

Reference LatLonbg

getPhoneLatLong

LatLong getPhoneLatLong(long timeMilliseconds,
                        int phoneNo)

Get's the LatLong of a specific hydrophone at a given time.

Parameters:

timeMilliseconds - time position needed for

phoneNo - Hydrophone number

Returns:

Hydrophone LatLong

getPhoneDepth

double getPhoneDepth(long timeMilliseconds,
                     int phoneNo)

Get's the depth of a specific hydrophone at a given time.

Parameters:

timeMilliseconds - time depth needed for

phoneNo - Hydrophone number

Returns:

Hydrophone depth

getPhoneTilt

double getPhoneTilt(long timeMilliseconds,
                    int phoneNo)

Get's the tilt of a specific hydrophone at a given time.

Parameters:

timeMilliseconds - time tilt needed for

phoneNo - Hydrophone number

Returns:

Hydrophone tilt

getPairAngle

double getPairAngle(long timeMilliseconds,
                    int phone1,
                    int phone2,
                    int angleType)

Get's the angle between a pair of hydrophones

Parameters:

timeMilliseconds - time angle is needed for

phone1 - First hydrophone

phone2 - Second Hydrophone

angleType - Type of angle - ANGLE_RE_NORTH; ANGLE_RE_SHIP; ANGLE_RE_ARRAY;

Returns:

angle in radians

getPairSeparation

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

Gets the distance between a pair of hydrophones in metres.

Parameters:

timeMilliseconds - time angle is needed for

phone1 - First hydrophone

phone2 - Second Hydrophone

Returns:

distance in metres.

notifyModelChanged

void notifyModelChanged(int changeType)
