Paper Abstract

This thesis introduced the identifying method of the laser target echo signal from the reflector which is used as the cooperate target and the optic modulator, build a mathematical model about the laser pulse coding and modulation, decoding and demodulation. Provied a demodulation method in frequency domain which do echo signal's FF1' with DSP high speed digital signal processor, this method can solve one frequency interference that cann't be eliminated in the time domain demodulation in the OOK system ,improve the system's detecting sensitivity and decrease the fault code rate, which was proved by theoretical analysis.
