Abstract
A method and apparatus for displaying radar data on a display monitor, wherein the monitor is divided into octants, and wherein the radar data defines a pie-shaped slice to be displayed within an octant on the monitor. The radar data has a center point which is defined as a point on an x-y plane, a radius r which is a defined as a number of displacement units in length extending radially from the center point, a starting angle .theta., a delta angle .differential..theta., radial displacement data which defines the color of groups of displacement units along the radius r for the slice, and a quantity Q which is the number of groups of radial displacement data within said radar data. The radar data is received by a data processing system and stored in memory. The video display monitor is updated by a screen refresh memory controlled by a graphics accelerator. The graphics accelerator receive the radar data for the slice to be displayed from the data processing system; determines the octant in which the slice is to be displayed; expands the radial displacement data into a color table which correlates the radial displacement data to pixel colors so that each displacement unit along the…
