Abstract

Radar display methods and systems include a display processing apparatus that includes a central processing unit and a programmable graphics processing unit. A rendering function program executable by the programmable graphics processing unit under control of the central processing unit generates a plurality of sequential display image frames for use in displaying at least a radar image on a display (e.g., by applying a decaying function to an accumulated radar history image frame and updating the accumulated radar history image frame).
