The design and implementation of PPI displaying system based on PC is described. The range-bearing polarizing coordination and raster displaying orthogonal coordination fast conversion al- gorithm is studied for real time displaying requirement of radar echo. Periodic echo data is applied to drive the descending of pixel color depth to satisfy fluorescence spots persistence vision analogue of traditional PPI display. Displaying data management based on layers is introduced for solution of over- lapping of digital map and trace. The design and algorithm described could meet the abovementioned function requirement. The research result is applied to some kind of detection system and works well.
