| Abstract: | In this paper,a new method to implement real-time display in windows operating system is presented.This method is implemented with multi-image data storage buffer,real-time interpolation and edge smoothing,and displaying page rotating technology.These technologies help the PPI and RHI display to present the real-time change of the weather more precisely,and improve real-time performance of the radar system significantly.The experiment results confirm the validity of this method. |
