Constructor Detail

FrequencyPattern

public FrequencyPattern(org.hipparchus.geometry.euclidean.threed.Vector3D eccentricities,
                        PhaseCenterVariationFunction phaseCenterVariationFunction)

Simple constructor.

Parameters:

eccentricities - phase center eccentricities (m)

phaseCenterVariationFunction - phase center variation function (may be null if phase center does not depend on signal direction)

Method Detail

getEccentricities

public org.hipparchus.geometry.euclidean.threed.Vector3D getEccentricities()

Get the phase center eccentricities.

Returns:

phase center eccentricities (m)

getPhaseCenterVariationFunction

public PhaseCenterVariationFunction getPhaseCenterVariationFunction()

Get the phase center variation function.

Returns:

phase center variation function (may be null if phase center does not depend on signal direction)

Since:

12.0

getPhaseCenterVariation

public double getPhaseCenterVariation(org.hipparchus.geometry.euclidean.threed.Vector3D direction)

Get the value of the phase center variation in a signal direction.

Parameters:

direction - signal direction in antenna reference frame

Returns:

value of the phase center variation
