A modulated laser detection system is designed to measure the zero time of launching.The best way is to adopt the correlation detection to enhance the signal-noise ratio(SNR) and the adaptive threshold,which can detect laser echo in the worst environment.The relationship among the optimal threshold level,SNR and the dynamic separation K is deduced.At SNR is 5.803dB,>1.4,the detection probability and the false alarm probability are 0.988,10-6respectively.
