Which display is typically used to show an alpha scan radar?

Explanation:
Radar information is best understood when the bearing around you and the distance from you are presented in a plan-view format. An alpha scan radar sweeps its beam in azimuth, and the most intuitive way to display those returns is on a circular, plan-position view where range grows outward from the center and bearing is shown around the edge. The Plan Position Indicator provides exactly that: a real-time, circular display of echoes plotted by distance and direction, giving a clear situational picture. A Sector PPI would show only part of the circle, a Circular display is too generic, and the standard term used for this type of presentation is the PPI.
