PhasedArrayGainPattern Class

A RadioFrequencyGainPattern for modeling planar phased array antennas. The phased array model consists of many radiating elements. Each element is modeled as an isotropic pattern. By modifying the excitation (amplitude and phase) of each element differently, a phased array antenna can electronically steer its maximum gain toward a particular direction or main radiation axis. A phased array antenna not only can steer its maximum gain in a particular direction, but it can also steer nulls toward other directions in an effort to prevent radiation to and from other directions. The act of altering each element's excitation is effectively accomplished through the assignment of weights to each element. This set of weights for a particular direction is called a steering vector and each weight is a complex number.

Constructors

	Name	Description
	PhasedArrayGainPattern	Initializes a new instance.
	PhasedArrayGainPattern(PhasedArrayGainPattern, CopyContext)	Initializes a new instance as a copy of an existing instance.
	PhasedArrayGainPattern(Double, Double, IEnumerablePhasedArrayElement, PhasedArrayBeamformer)	Initializes a new instance.
	PhasedArrayGainPattern(Double, Double, IEnumerablePhasedArrayElement, PhasedArrayBeamformer, PhasedArrayElementFactor)	Initializes a new instance.

Properties

	Name	Description
	BackLobeSuppression	Gets or sets the phased array back lobe suppression value applied to the antenna gain for directions with a negative z component (back lobe).
	Beamformer	Gets or sets the phased array beam former.
	DesignFrequency	Gets or sets the phased array design frequency. The design frequency determines the wavelength used to space the elements in the xy plane of the antenna.
	ElementFactor	Gets or sets the element factor. If set to null, the element factor will not be applied to the antenna gain pattern.
	ElementPattern	Gets the list of PhasedArrayElement instances which form the phased arrays element pattern.
	IsFrozen	Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so. (Inherited from DefinitionalObject.)

Methods

	Name	Description
	CheckForSameDefinition(BaseGainPattern)	Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object). (Inherited from RadioFrequencyGainPattern.)
	CheckForSameDefinition(DefinitionalObject)	Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object). (Inherited from BaseGainPattern.)
	CheckForSameDefinition(PhasedArrayGainPattern)	Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
	CheckForSameDefinition(RadioFrequencyGainPattern)	Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object). (Overrides RadioFrequencyGainPatternCheckForSameDefinition(RadioFrequencyGainPattern).)
	Clone	Clones this object using the specified context. (Overrides DefinitionalObjectClone(CopyContext).)
	ComputeCurrentDefinitionHashCode	Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the CheckForSameDefinition(DefinitionalObject) method. (Overrides RadioFrequencyGainPatternComputeCurrentDefinitionHashCode.)
	EnumerateDependencies	Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class. (Overrides DefinitionalObjectEnumerateDependencies(DependencyEnumerator).)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	Freeze	Freezes this object. Further attempts to modify it will result in an ObjectFrozenException. (Inherited from DefinitionalObject.)
	FreezeAggregatedObjects	Called by Freeze to also freeze any objects that are considered to be a part of this object. Derived classes which contain additional aggregated objects MUST override this method, call the base implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be frozen in this method are frequently created in this object's constructor and are not settable via properties. (Overrides DefinitionalObjectFreezeAggregatedObjects.)
	GetAntennaGainEvaluator(Vector, Axes, Signal)	Get an evaluator for the gain that would be applied to the given sample signal based on the given geometry. (Inherited from BaseGainPattern.)
	GetAntennaGainEvaluator(EvaluatorGroup, Vector, Axes, Signal)	Get an evaluator for the gain that would be applied to the given sample signal based on the given geometry. (Inherited from BaseGainPattern.)
	GetApplyAntennaGainEvaluator	Get an evaluator which can modify a set of input signals based on link geometry and the gain pattern. (Overrides BaseGainPatternGetApplyAntennaGainEvaluator(EvaluatorGroup, Vector, Axes, ISignalSource, SignalPropagationGraph).)
	GetDefinitionHashCode	Gets a hash code representing the definition of this object. (Inherited from DefinitionalObject.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetService	Gets the service object of the specified type. (Inherited from BaseGainPattern.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsSameDefinition	Determines if this object has the same definition as another object. (Inherited from DefinitionalObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ThrowIfFrozen	Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object. (Inherited from DefinitionalObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
