Classic 2D intensity plots of RCS are simply a 2D grid plot where colors indicate the magnitude of the plotted variable for any particular XY-variable combination. POSTFEKO may be used to plot a more insightful 3D rendering of this information. The intensity in this video is plotted on a spherical co-ordinate system surrounding the object under investigation. At the centre of the viewing window the magnitude of the RCS at that point corresponds to the current view of the target, which is visible by making the RCS rendering slightly translucent. This visualization helps the viewer learn intuitively which aspect of the target has the biggest RCS.
