摘要
文中针对激光水下测距信噪比低、回波信号提取困难的问题,采用数字检测技术进行处理,大幅提高了检测信噪比和激光水下测距能力,同时拓宽了激光测距的应用范围。
The SNR of faint signal is very low in the underwater laser pulse ranging, so it is very difficult to recognize the echo wave. This paper introduces digital detection method and uses it to process the signal, and we get good resuits. This study greatly improves the ability of underwater laser ranging.
