| Abstract: | The SNR of faint signal is very low in the long distance laser ranging or bad circumstance laser ranging, so it is very difficult to recognize the echo wave. This paper introduces digital correlation detection method and uses it to process the signal. Single signal correlation and multi signal correlation are simulated and calculated with laser ranging radar and a good results is got. This study will help to greatly improve the ability of laser ranging radar. |
