Constructor Detail

OneDVariation

public OneDVariation(double polarStart,
                     double polarStep,
                     double[] variations)

Simple constructor.

Parameters:

polarStart - start polar angle

polarStep - between grid points

variations - sampled phase center variations

Method Detail

value

public double value(double polarAngle,
                    double azimuthAngle)

Evaluate phase center variation in one signal direction.

Specified by:

value in interface PhaseCenterVariationFunction

Parameters:

polarAngle - angle from antenna axial direction (zenith angle for receiver antennas, nadir angle for GNSS satellites antennas)

azimuthAngle - angle around axial direction

Returns:

phase center variation in the signal direction (m)
