Signature propagator used in the infrared sensor domain. This propagator returns an apparent signature based on the absolute signature * 1000 / distance in meters plus any enviromental effects. This means that an apparent signature of 1.0 is observed when the distance from the target in km equals the target's absolute signature. This propagator checks for intersections with smoke objects which could further degrade the apparent signature of an object. This propagator requires a DtInfraredSignaturePropagatorDescriptor descriptor type.

Member Function Documentation

virtual void DtInfraredSignaturePropagator::init ( )

overridevirtual

Assigns myInfraredPropagatorDescriptor by casting the result of descriptor().

Reimplemented from DtStandardSignaturePropagator.

virtual double DtInfraredSignaturePropagator::calculateApparentSignature	(	double	absoluteSignature,
		const DtSignaturePropagatorArgs &	args,
		bool *	dataAvailable = `nullptr`
	)		const

overridevirtual

Takes the given absolute signature and applies to it the effects of the environment.Will check for smoke objects that could degrade the signature or block line of sight altogether. If the DtPhysicalWorld::checkLineOfSight reports that there is no data available (i.e. it is still being paged in), 0 will be returned.

Reimplemented from DtStandardSignaturePropagator.

virtual double DtInfraredSignaturePropagator::calculateSmokeReductionFactor	(	double	apparentSignature,
		const DtVector &	databaseStartPoint,
		const DtVector &	databaseEndPoint
	)		const

virtual

Will look for any smoke intersections between sensor and object If found will reduce the apparent signature further.

static DtSignaturePropagator* DtInfraredSignaturePropagator::create	(	const DtSignaturePropagatorDescriptor *	desc,
		DtPhysicalWorld *	physicalWorld
	)

static

Creates a new instance of this class, calls init() on it, and returns it.

		const DtVector &	geocEndPoint,
		const DtRwGaussianPuffData &	puff,

Given a chord and a puff, determine the intersection.
