摘　　要：在自由空间中将接收到的距离为10km调制的微弱激光信号,利用PIN光电探测器转变成电信号,经过快速采集系统,通过DSP6416(TMS320C6416T)HPI接口传送到DSP6416中。在DSP6416内部对淹没在噪声里的微弱信号进行放大,低通滤波,改进的自相关运算等,形成一种独特算法,获取微弱激光信号信息。The modulated weak laser signal received from 10 km distance in free space is converted into electrical signal by PIN photoelectric detector , which is transferred to DSP6416（TMS320C6416T） by fast data acquisition system and HPI interface.The weak signal overwhelmed in the noise is amplified , filtered and operated with improved autocorrelation regularly within DSP6416. In conclusion, a special algorithm is proposed and the laser signal communication is captured.
