The measuring principle of echo sounder

- Jul 24, 2017 -

Echo detection equipment is the first class of underwater acoustic instruments, this device has been widely used. All of these devices share a common feature: they use a set of transmit transducers to emit sound waves underwater, so that the sound waves propagate along the sea water until they come back to the target and then reflected back. The reflected sound is received Receiver. And then by the sonar or computer processing received signal, and then determine the target parameters and types.

Echo detection devices are also different, so they tend to use different transmit and receive transducers, so the sound signal frequency and waveform are also different. In fact, the difference between the different echo detection equipment, the main difference is mainly in the echo signal on the different processing methods. Now, this principle has been widely used in the following hydropower equipment: echo depth sounder, side scan sonar, acoustic Doppler flow meter and fish detector and so on. The invention and use of these instruments and equipment for the study of the ocean, the development of the ocean, the use of the ocean made an important contribution.
