本文介绍了在合成孔径雷达光学处理器上所加的一套CCD图像存贮与显示系统。该系统采用线阵CCD器件,对运动的图像采样,其输出信号经A/D变换后,在行同步逆程期间将数字信号逐行写入存贮器中去;在行同步正程期间再将数据读出,经假彩色编码及D/A变换后即可在彩色监示器上显示出滚动的假彩色图像。该系统除了能够即时观察图像之外,还为进一步数字图像处理提供了方便。
This article describes a set of CCD image storage and display system added to the synthetic aperture radar optical processor. The system uses a linear CCD device, the image of the moving sample, the output signal after A / D conversion, during the line synchronization of the digital signal will be written into the memory line by line to go; during the line synchronization and then The data read out, false color coding and D / A conversion can be displayed on the color monitor scrolling false color image. In addition to being able to view the images instantly, the system also provides convenience for further digital image processing.
