Syntax
public AttributeVariable< DistanceVariation > DistanceVariation { get; set; }Property Value
Type: An attribute variable that returns a value of type DistanceVariation.
Default: Constant
An enumeration value that tells how the range varies with direction: Constant or PhasedArray.
Default: Constant
An enumeration value that tells how the range varies with direction: Constant or PhasedArray.
Remarks
The possible values are
Constant, which gives a constant range = MaxDistance.
 |
distanceVariation = Constant.
PhasedArray, whose range is MaxDistance * sqrt( max(0, cos(a))), where a is the current horizontal angle difference from the PictureDirection.
 |
distanceVariation = PhasedArray, pictureDirection = 90 (east).
When representing a phased-array radar system, the PictureWidth is often set to 120°:
 |
distanceVariation = PhasedArray, pictureDirection = 90 (east), pictureWidth = 120.
and the SecondPictureBackwards can be True:
 |
distanceVariation = PhasedArray, pictureDirection = 90 (east), pictureWidth = 120, secondPictureBackwards = True.
