supersonic echo sounder

With the development of the electronic technology especially the digital signal processor,the echo sounder is stepping into the digital age.

随着电子技术特别是数字信号处理器的迅速发展,回声测深仪进入了数字化时代;计算机技术与数字信号处理器的结合,使测深仪一改其单一的旧"面孔",人机操控显示界面、结构组成呈多样性。

Echo Sounder is a kind of acoustic measuring depth equipment, which can measure depth with the time between transmitted wave and echo on condition in which the speed of ultrasonic is fixed.

回声测深仪是用来测量水深的一种声学测量设备,其以水中超声波的传播速度为确定条件,利用发射波与反射回波时间差来测量水深。
