| Abstract: | 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 ke... |
