Study On A Multi-Pulse Laser Ranging

In the dissertation a multi signal laser ranging is designed.The SNR of fainal signal is very low in the long distance laser ranging , so it is very difficult to recognize the echo wave .The digital processer method is introdued in this dissertation uses it to process the signal. multi signal correlation are simulated and calculated with laser ranging and good results is got.In the dissertation a digital processer of narrow laser echo pulse based on 200MHz is designed. It solves the technological difficulty of high speed ADC . Highspeed DSP chip is used for processing data . It supply the hardware tool. By the measure , the performance of laser ranger is remarkably improved...
