| 摘 要： | 利用二元光电探测器接收激光脉冲信号，然后根据互相关检测的原理设计了信号处理电路，对接收到的信号进行处理，使其信噪比得到改善。在实验中选用不同的延迟时间τ进行检测，并给出了实验结果，且对实验结果进行了比较。实验表明，根据实际情况选择正确的延迟时间，可以达到较高的信噪改善比，满足大多数使用需求。

| Abstract: | A binary photodetector receives the laser pulse signal, then a signal processing circuit based on cross-correlation detection processes the received signal so as to improve SNR. In the process of experiment, detection is carried out in different delays, and different detection results are compared in this paper. It is shown by the experiment that getting higher SNIR is feasible as long as the delays are selected properly. |

| Keywords: | laser pulse pulse signal correlation detection delay SNIR |
