基于动态数据表的实时高分辨率雷达回波显示

对高分辨率雷达信号的光栅扫描显示不仅需要高速信号处理,而且需要高速图形显示。提出并构建了"动态数据表"及基于该数据表的"完全相对查表法"显示算法,从而实现了高分辨率(1024*1024)雷达回波的实时处理、显示。此方法适用于在光栅扫描显示器上实现雷达回波的全屏、长余辉消隐.在PC计算机上模拟雷达回波显示,此方法的优点更加突出。

Real Time High-Resolution Radar Echo Display Based on Dynamic Data Tables

For the raster scan display of high-resolution radar signal,high-speed signal processing is necessary,but high-speed graphics display is also very important.To realize the real-time procession and display of high-resolution(1024*1024)radar echo signal,Dynamic Data Tables were proposed and established,then an algorithm named "Absolute Relative Search Table "based on the data tables.These tables and the algorithm involved were proved to be applicable to radar echo with full screen and long afterglow on raster scan displayer,especially in using PC to simulate radar display.
