Radar PPI-Scope
The PPI-scope shown in this figure, is
by far the most used radar display. It is a polar coordinate display
of the area surrounding the radar platform. Own position is
represented as the origin of the sweep, which is normally located in
the center of the scope, but may be offset from the center on some
sets. The ppi uses a radial sweep pivoting about the center of the
presentation. This results in a map-like picture of the area covered
by the radar beam. A long-persistence screen is used so that the
display remains visible until the sweep passes again.
