Constructors
  NameDescription
Public methodSphericalTabularMonostaticCrossSectionScatteringCoefficient(SphericalTabularMonostaticCrossSectionScatteringCoefficientCrossSectionScatteringMatrixSphericalTable)
Initializes a new instance.
Public methodSphericalTabularMonostaticCrossSectionScatteringCoefficient(Double, ComplexCrossSectionScatteringCoefficient)
Initializes an instance given an array of cone angles, in radians, and an array of monostatic cross section values represented as a complex 2x2 scattering matrix. This represents a symmetrical pattern about the z-axis. For a given cone angle, the cross section is the same for every clock angle about the z-axis.
Public methodSphericalTabularMonostaticCrossSectionScatteringCoefficient(Double, Double)
Initializes an instance given an array of cone angles, in radians, and an array of monostatic cross section values, in meters squared. This represents a symmetrical pattern about the z-axis. For a given cone angle, the cross section is the same for every clock angle about the z-axis.
Protected methodSphericalTabularMonostaticCrossSectionScatteringCoefficient(SphericalTabularMonostaticCrossSectionScatteringCoefficient, CopyContext)
Initializes a new instance as a copy of an existing instance.
Public methodSphericalTabularMonostaticCrossSectionScatteringCoefficient(Double, Double, ComplexCrossSectionScatteringCoefficient)
Initializes an instance given an array of clock angles, an array of cone angles, and a two-dimensional array of monostatic cross section values represented as a complex 2x2 scattering matrix. Clock angle is defined as the azimuth angle from the positive x-axis to the orthogonal projection of the point in the x-y plane. Cone angle is defined as the zenith angle from the positive z-axis to the point. The cross section values array must be arranged such that the rows of the array represent clock angle cuts through the pattern and the columns represent cone angle cuts. Therefore, the first dimension of the cross section values array must be the same size as the clock angles array and the second dimension of the cross section values array must be the same size as the cone angles array. If duplicate clock/cone angle points are found, the first one that is found will be kept and subsequent clock/cone angle points are ignored. For example, if the clock angle array contains a value of 0 degrees and a value of 360 degrees (same cut through the sphere) all of the cone angles at clock angle equal to 360 degrees will be ignored.

Initializes an instance given an array of clock angles, an array of cone angles, and a two-dimensional array of monostatic cross section values, in meters squared. Clock angle is defined as the azimuth angle from the positive x-axis to the orthogonal projection of the point in the x-y plane.

Methods
  NameDescription
Public methodApplyScatteringCoefficient(UnitCartesian, UnitCartesian, UnitQuaternion, Signal)
Applies the scattering coefficient to the input signal.
(Overrides ScatteringCoefficientApplyScatteringCoefficient(UnitCartesian, UnitCartesian, UnitQuaternion, Signal).)
Public methodApplyScatteringCoefficient(UnitCartesian, UnitCartesian, UnitQuaternion, Signal, Signal)
Applies the scattering coefficient to the input signals.
(Overrides ScatteringCoefficientApplyScatteringCoefficient(UnitCartesian, UnitCartesian, UnitQuaternion, Signal, Signal).)
Protected methodCheckForSameDefinition(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 ScatteringCoefficient.)
Protected methodCheckForSameDefinition(ScatteringCoefficient)
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 ScatteringCoefficientCheckForSameDefinition(ScatteringCoefficient).)
Protected methodCheckForSameDefinition(SphericalTabularMonostaticCrossSectionScatteringCoefficient)
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.

Public methodClone
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).)
Protected methodComputeCurrentDefinitionHashCode
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.

Computes the scattering coefficient in the supplied monostatic direction.
Protected methodComputeScatteringCoefficient(UnitCartesian)
Computes the scattering coefficient in the supplied monostatic direction.

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.

Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Public methodFreeze
Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.
(Inherited from DefinitionalObject.)
Protected methodFreezeAggregatedObjects
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.

(Inherited from DefinitionalObject.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodThrowIfFrozen
Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)

Remarks
The 2x2 complex scattering matrix cross section value is evaluated by first computing the monostatic direction vector, which is the bisection of the incident and reflected unit vectors. Then from the monostatic direction, the cone angle and clock angle are computed in the spherical coordinate system. The cross section value is the obtained by interpolating the cross section table data using the computed cone and clock angles.
