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相关处理电路对接收到的信号进行处理 ,使其信噪比 (SNR)得到改善。实验表明 ,对于淹没在噪声中的信号 ,通过相关处理后其信噪比可以达到 2 6dB以上。可以满足大多数使用需求。
We receive the laser pulse signal with the binary photo-electric detector,deal the signal with the circuit designed on the basis of correlation detection to improve SNR.The experimental results show that improved SNR can reach 26dB while the signal submerged in noise is processed by the circuit,and it can satisfy the application requirement under most circumstance.
