Detailed Description

A set of utilities that perform generic calculations among WSF objects. The non-exportable version contains link-16 specific algorithms.

ConvertLink16_TrackQualityToSphericalCovariance()

UtCovariance * WsfNonExportableUtil::ConvertLink16_TrackQualityToSphericalCovariance ( double aLink16_TrackQuality )

static

Given a Link-16 track quality (see mil-std 6016C, pp 303-305), stuff the equivalent variance into the diagonals of a 3x3 matrix, producing an equivalent spherical covariance matrix.

Parameters

aLink16_TrackQuality

the track quality computed according to the 6016C standard and normalized into the range 0-1.

Returns

a 3x3 matrix with the diagonal elements set to the variance associated with the track quality. This is a "pseudo" covariance matrix that has a spherical representation.

Note

It is the responsibility of the caller to delete the returned matrix.

GetLink16_TrackQuality() [1/3]

double WsfNonExportableUtil::GetLink16_TrackQuality ( double aSimTime, const WsfTrack & aTrack )

static

Compute the Link-16 track quality for a given track. This method does not currently support the sensor platform's location error. The given track should have a valid state or measurement covariance for accurate computation.

Parameters

aSimTime	The simulation time.
aTrack	The track used to compute the Link-16 track quality.

Returns

the WSF-normalized Link-16 track quality, in the range 0.0-1.0 (not 0-15).

GetLink16_TrackQuality() [2/3]

double WsfNonExportableUtil::GetLink16_TrackQuality ( double aSimTime, double aTrackUpdateTime, const UtCovariance & aCovar, double aSpeed = 0.0 )

static

(Deprecated) Compute the Link-16 track quality for a given track. This method does not currently support the sensor platform's location error. The given track must have a valid covariance matrix.

Parameters

aSimTime	The current simulation time.
aTrackUpdateTime	Simulation time at which the track was previously updated.
aCovar	The covariance that is used to create the track quality.
aSpeed	The current estimated speed of the tracked object (optional).

Returns

the WSF-normalized Link-16 track quality, in the range 0.0-1.0 (not 0-15). If the track quality cannot be computed, zero is returned.

GetLink16_TrackQuality() [3/3]

double WsfNonExportableUtil::GetLink16_TrackQuality ( double aSimTime, double aTrackUpdateTime, double aVarTp, double aSpeed = 0.0 )

static

Compute the Link-16 track quality for a given track. This method does not currently support the sensor platform's location error.

Parameters

aSimTime	The current simulation time.
aTrackUpdateTime	Simulation time at which the track was previously updated.
aVarTp	The average uncertainty in position squared (average variance).
aSpeed	The current estimated speed of the tracked object (optional).

Returns

the WSF-normalized Link-16 track quality, in the range 0.0-1.0 (not 0-15). If the track quality cannot be computed, zero is returned.
