Since the graphics processor of common X86 platform does not support the display function of multi-layer graphics, this paper proposes to combine the Qt Graphics-view framework with OpenGL pixels operation function and utilizes the graphics memory under the Linux system to achieve the layered and efficient display based on the radar information. The proposed approach can effectively realize the main functions of radar display and control system, including the radar Plan Position Indicator (PPI) display, target glint in warning area, and Automatic Identification System (AIS) target management and display. The experimental results prove that the proposed approach has the advantages of high efficiency, smooth image update, and low hardware requirements. In addition, the proposed approach has been successfully applied to a typical shipborne radar navigation system.
