  • Received Date: June 23, 2003

  • Published Date: May 24, 2004
  • We receive the laser pulse signal with the binary photo-electric detector,deal the signal with the circuit designed on the basis of correlation detection to improve SNR.The experimental results show that improved SNR can reach 26dB while the signal submerged in noise is processed by the circuit,and it can satisfy the application requirement under most circumstance.
