动态数据表在雷达模拟系统中的应用

The Application of Dynamic Data Table in Radar Simulation System

动态雷达回波的长余辉消隐处理和显示是雷达模拟器的关键技术。在动态数据表的基础上,提出了用位图模拟雷达回波信号的方法和过程,及模拟动态雷达回波的全屏长余辉消隐算法。进而提出了全屏数据表和全屏查表法,保证了雷达模拟系统动态数据表的实时更新和显示。最终实现了高分辨率(1024*1024)雷达模拟器动态回波的长余辉实时处理、显示。使用普通PC机在高分辨率显示器上的仿真验证了上述方法的有效性。

Dynamic radar echo long afterglow is the key technical of radar simulator. Base on the dynamic data table, a method of radar echo signal simulated by bitmap was discussed, and full screen long afterglow algorithm was given. Farther, full screen data table and full screen search table algorithm were proposed and then established. They guarantee the dynamic data table Real-time refresh and display, and realize Real-time high-resolution（1024＊1024） radar simulator dynamic echo long afterglow＇s procession and display. Through PC emulation, the design method is proved practical and efficient.
