ABSTRACT:
A display system utilizing a non-linear raster generator is disclosed. As is conventional in raster scan displays, the scanning is controlled by two electrical signals arbitrarily designated the X and Y deflection signals. In the preferred embodiment, two memories are used to store signals which provide constants to control the amount of the non-linearity of the raster. These constants are processed to generate X and Y deflection signals which are generally hyperbolic in nature. This type of display is particularly useful for displaying mapping signals produced from airborne doppler radar.
