摘　　要：介绍了一种DSP数字处理器TMS320DM642在移动平台ATP技术中的应用。DSP处理CCD采集的图像信号,并将相应信息实时反馈给电机控制部分,立即作出相应调整从而控制CCD运动,使光斑落在视场中心。移动平台ATP(信标光捕获跟踪瞄准)技术是实现空间激光通信的关键技术,在卫星和航空航天等大容量通信方面具有巨大应用前景。The paper introduces the application of DSP TMS320DM642 in ATP technology ATP among moving platforms. DSP is used mainly for image signal processing, which are captured image signals from CCD. The results from the DSP are transmited to the part of controller in time. The controller makes the two-axis platform,which is equipped with CCD,adjusts real time according to the results. So that to make sure the beacon continually appears on the center of CCD.The technology of ATP（Acquisition, Tracking, Pointing） is the key technology for space laser communication among moving platforms and has great applied future in the area of large data communication, such as satellite,avigation and spaceflight.
