Description

Technical Field

[0001] The present invention relates to the technical field of underwater signal processing equipment, and in particular to an underwater communication signal processing device and a method for using the same. Background Art

[0002] Sound waves are needed for observation and measurement in water. This is because the effective range of other detection methods is very short. The penetration ability of light in water is very limited. Even in the clearest sea water, people can only see objects within ten to several dozen meters. Electromagnetic waves also attenuate too quickly in water, and the shorter the wavelength, the greater the loss. Even with high-power low-frequency electromagnetic waves, they can only propagate tens of meters. However, the attenuation of sound waves propagating in water is much smaller. A bomb weighing several kilograms explodes in a deep-sea sound channel, and the signal can be received 20,000 kilometers away. Low-frequency sound waves can also penetrate several thousand meters of strata on the seabed and obtain information in the strata.

[0003] Existing underwater communication signal processing components are usually directly fixed on the support plate inside the device. However, underwater communication signal processing components are easily affected by the underwater environment and may malfunction. When a problem occurs, the entire device needs to be taken out and then the communication signal processing components need to be disassembled for maintenance, which causes great trouble to the maintenance personnel. The receiving end direction of existing underwater communication signal processing components is generally fixed. By changing the receiving end to receive signals at different depths underwater, multi-dimensional signal acquisition cannot be achieved, which affects the effect of communication signal processing. For this reason, we propose an underwater communication signal processing device and a method for using the same. Summary of the invention
