A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...
The constant altitude plan position indicator, better known as CAPPI, is a radar display which gives a horizontal cross-section of data at constant altitude. It has been developed by McGill University in Montreal by the Stormy Weather Group [1] to circumvent some problems with the PPI: Altitude changing with distance to the radar.
This image shows a modern PPI display in use, with the islands and ground surrounding the ship in green. The current direction of the radar can be seen as the dotted line pointing northwest. The PPI display provides a 2-D "all round" display of the airspace around a radar site. The distance out from the center of the display indicates range ...
Unlike the earlier system where radar data was forwarded by telephone and plotted on a map, GCI radars combined all of these functions into a single station. The PPI was in the form of a 2D top-down display showing both the targets and the intercepting night fighters. Interceptions could be arranged directly from the display, without any need ...
A high-resolution, north-oriented, coloured radar picture is displayed on PC display. The radar display can either be in a Plan position indicators (PPI) display, or a B-Scope display. The display also has provision for digital geographic map overlay, which allows the target data to be integrated with tactical data for use by ground forces and ...
