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 ...
Graphics represented as a rectangular grid of pixels. Rasterization Converting vector graphics to raster graphics. This terms also denotes a common method of rendering 3D models in real time. Ray casting Rendering by casting non-recursive rays from the camera into the scene. 2D ray casting is a 2.5D rendering method. Ray marching
AN/APS-115 is a development of AN/APS-80A, [4] and it is the first attempt of digitization by providing digital input into the digital combat system installed on the P-3. . Other improvement over the original AN/APS-80 included the integration of two separate AN/APS-80A radar into a single unit via a single planar position indicator (PPI) disp

Radar returns brightened the video. Search and weather radars have a circular display (Plan Position Indicator, PPI) that covers a round screen, but this is not technically a raster. Analog PPIs have sweeps that move outward from the center, and the angle of the sweep matches antenna rotation, up being north, or the bow of the ship.
The illumination models listed here attempt to model the perceived brightness of a surface or a component of the brightness in a way that looks realistic. Some take physical aspects into consideration, like for example the Fresnel equations, microfacets, the rendering equation and subsurface scattering.
