摘要
从工程实践角度介绍了两种混频电路在吊放声纳的听音、显示信号处理过程中的应用,并经试验验证了混频技术在抑制噪声干扰,提高检测信噪比方面的作用。
Two types of mixer circuit used for audio and display signals processing to the dipping sonar is introduced in this paper from the point of view engineering.The effects on interference suppression and noise-signal ratio improvement were validated by experiments.
