Detailed Description

The Class CDSS. This is a dedicated class that only uses the CD3D (CDCylinder) detection algorithm. The more general form is CDSSCore, which may utilize arbitrary Detection3D detection algorithms.

Usage: CDSS cdss = new CDSS(); cdss.setDistance(5,"NM") cdss.setHeight(950,"ft") boolean det = cdss.detection(so,vo,si,vi,T);

Constructor & Destructor Documentation

CDSS() [1/3]

larcfm::CDSS::CDSS

(

larcfm::CDSS::CDSS	(	double	D,
		const std::string &	ud,
		double	H,

Member Function Documentation

conflict()

bool larcfm::CDSS::conflict	(	const Position &	so,
		const Velocity &	vo,
		const Position &	si,
		const Velocity &	vi,
		double	B,
		double	T
	)		const

Determines if two aircraft are in conflict within a given lookahed time (internal units). This function DOES NOT compute time interval of conflict.

Parameters

so	the position of the ownship
vo	the velocity of the ownship
si	the position of the intruder
vi	the velocity of the intruder
T	lookahead time in internal units [s] (T > 0)

Returns

true, if the aircraft are in conflict in the interval [0,T].

Determines if two aircraft are in conflict within a given lookahed time (internal units). This function DOES NOT compute time interval of conflict.

Parameters

s	the relative position of the aircraft
vo	the velocity of the ownship
vi	the velocity of the intruder
T	lookahead time in internal units [s] (T > 0)

Returns

true, if the aircraft are in conflict in the interval [0,T].

detection()

bool larcfm::CDSS::detection	(	const Position &	sop,
		const Velocity &	vo,
		const Position &	sip,
		const Velocity &	vi,
		double	T,
		const std::string &	ut
	)

Detects a conflict that lasts more than filter time within a given lookahed time and computes the time interval of conflict (internal units). If timeIn() == 0, after this function is called then aircraft is in loss of separation.

Parameters

so	the position of the ownship
vo	the velocity of the ownship
si	the position of the intruder
vi	the velocity of the intruder
T	the lookahead time in internal units ut (T > 0)

Returns

true, if there is a conflict that last more than the filter time in the interval [0,T].

getCriticalTime()

double larcfm::CDSS::getCriticalTime

(

const std::string &

ut

)

const

Return the critical time for the conflict, as determined by the core detection algorithm. This is generally not the traditional time of closest approach.

getTimeIn()

double larcfm::CDSS::getTimeIn

(

const std::string &

ut

)

const

Time to loss of separation in explicit units.

Parameters

ut	the explicit units of time

Returns

the time to loss of separation in explicit units [ut]. If time is negative then there is no conflict.

getTimeOut()

double larcfm::CDSS::getTimeOut

(

const std::string &

ut

)

const

Time to recovery of loss of separation in explicit units.

Parameters

ut	the explicit units of time

Returns

the time to recovery of loss of separation in explicit units [ut].

Time to recovery of loss of separation in explicit units.

Parameters

ut	the explicit units of time

Returns

the time to recovery of loss of separation in explicit units [ut]. If timeOut is zero then there is no conflict. If timeOut is negative then, timeOut is infinite.

lossOfSeparation()

bool larcfm::CDSS::lossOfSeparation	(	const Position &	sop,
		const Velocity &	vo,
		const Position &	sip,
		const Velocity &	vi
	)		const

Determines if two aircraft are in loss of separation. This function DOES NOT compute time interval of conflict.

Parameters

so	the position of the ownship
vo	velocity of ownship
si	the position of the intruder
vi	velocity of intruder

Returns

true, if the aircraft are in loss of separation.
