摘　　要：研制了多抽头TDI(时间延时积分)CCD的图像合成及信号处理系统,该系统能够实现8抽头的可见光图像合成,并采用两点校正法对图像进行非均匀性校正。该硬件主要由内嵌大容量RAM的FPGA和ARM处理器组成,数据合成和数据处理的速度高达25 MHz。Imaging synthesis of a multi-tap TDI （Time Delay Integration） CCD imager and its signal processing system are fabricated. This system can realize the imaging synthesis of eighttaps＇ visible light, using double-point correction to carry out the images＇ non-uniformity adjustment. Its hardware is mainly composed of FPGA （Field programmable logic devices） embedded with high-capacity RAM and the ARM processor, and the speed of data synthesis and processing reaches as high as 25 MHz.
