摘　　要：针对VTS雷达一次回波的处理及显示问题,提出了优化坐标快速转换及回波数据实时显示处理的方案。该方案采用环形队列和二级缓存机制解决了实时接收数据丢包问题;并采用远区补偿方法结合Directx3D技术下的多图层融合解决了由坐标转换带来的图像缺损产生的摩尔纹,同时对回波显示进行了修正,且实现了多量程下的回波显示。该设计在节省系统资源的同时取得了更快的显示速度和更好的显示效果,并已在实际工程中得到了验证。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.
