Abstract:

A scheme of optimal flexible ordinate transform and echo real time processing and display is proposed to address the VTS radar raw data processing and display.Real-time receive data loss problem has been solved using circle queue and two-level cache architecture.Through PPI display based on Directx3D technology and far region compensation method combined with multi-graph layer fusion solve the image defects caused by ordinate transform,the echo display is corrected,and echo displaying in multi-range switch is achieved.VTS radar PPI display based on Directx3D technology saves system resource with higher display speed and better display effect.This method is verified in practical project.
