Chapter 338: Sonar deception device

Sound waves are received on the back of the board, so the "diffuse reflection" principle will also dissipate this sound wave, and a sound wave with exactly the same frequency will be emitted on the front of the board.
In other words, this sonic diffuse reflection coating can effectively avoid being detected by sonar, allowing the objects coated with the coating to achieve a feeling of "disappearing out of thin air".
Although the working principle of this kind of coating is more complicated, it is essentially a concealed method.
It’s just that it’s not as special as a sound-absorbing metal, which absorbs all the sound, but while absorbing the sound, it generates sound waves on the back, hits obstacles, and then launches through the front.
Similar to the so-called "optical stealth", which is the same as the optical stealth module mounted on the third-generation steel armor and the optical stealth drone array.
Optical stealth is to twist the photon at a specific angle through the refraction of light, so that the visible light cannot reach there, so as to achieve stealth at the optical level.
The same is true for acoustic diffuse reflection coatings.
The existence of this kind of coating also makes it possible to hide underwater. If the shell of a submarine can be painted with a layer of this stuff, then the sonar will be completely undetectable.
Because no matter how the sound wave is emitted to the coating, the same sound wave will be emitted from the back and then reflected back through the front intact.
The sound waves that were shot out simply couldn't reach the corresponding object at all, but hit the seabed directly, so that the object could be recognized and there would be ghosts.
The submarine is brushed with this sonic diffuse reflection metal, then the submarine will truly become the so-called "night assassin", and the submarine's reputation will be soared in history.
By then, the means of detection of submarines by various countries will not be sonar.
It is a magnetic anomaly detector (the metal hull interferes with the earth’s magnetic field to cause a change in the magnetic field), an infrared thermometer (detects the heat emitted by the submarine to heat the surrounding seawater, causing the seawater temperature to rise), and radar (detects the periscope and vent pipe exposed to the surface ), wake anomaly detection, even using biological detection methods (dolphins), etc.
In any case, the sonic diffuse reflection coating that Ye Fan exchanged today will definitely rewrite the current pattern of naval battles.
Of course, the science and technology used must be gradual, otherwise this kind of black technology that looks directly like a "zenith star" will be ghosts without being suspected.
Datang Technology has now risen, and it needs more time to stabilize and establish a correct image in front of the people across the country.
In the end, it is necessary to adopt a specific plan to gradually eliminate the labor force of the factory, and assume the role of living security for the eliminated population, which is to "raise" them.
When your subordinates support millions of people, then you are truly invincible.
When your living habits are completely linked to a company, and even the security of life comes from it, the people with vested interests who don't want the company to have trouble are often those with vested interests, but this vested interest may have millions of people.
When these technologies are brought out again, even if some people will suspect, even if some people are plotting wrong, they will definitely not dare to act rashly.
What Datang Technology has to do now is to wait.
Tamron Chip Group needs time to upgrade the lithography machine from 22nm to 7nm, thus completely replacing the position of TSMC and other chip foundries.
Datang Heavy Industry also needs a certain amount of time to complete the industrial upgrade, completely eliminating manual labor and replacing all production lines with intelligent robots. This also requires waiting.
Even with Ye Fan's technology, it would take a certain amount of time to spin off a department from Datang Heavy Industries and set up Datang Arms Company to sell high-tech arms, depending on Ye Fan's ability to control Baidao.
In any case, Datang Technology is not short of money now, it is short of time.
"Origin, at that time, you will order Datang Heavy Industry's production line to produce a new coating based on the material I said. After it is produced, it will be coated on the submarine cable.
And all the underwater submarines and robots involved in the construction will do. This project is a bit huge. In terms of funds, I will allocate another 10 billion to you. Although the materials are a bit expensive, it is enough. "Ye Fan spoke to Origin from inside the steel armor.
"Okay master, I will arrange for Chairman Lin Wei to go to major mineral companies to purchase raw materials. It's just that the kind of coating you mentioned, the master,
In essence, it is still a relatively active metal, which will spontaneously ignite when it encounters water, so an additional layer of waterproof coating is needed, which will increase the budget by 20%. "
Soon, after some analysis, Origin said to Ye Fan.
"Well, I will allocate another 2 billion to you. If it is not enough, you can continue to find me." Ye Fan also waved his hand, and directly agreed.
After all, with regard to security, no matter what, the money can't be saved. After all, who knows what happens if security measures are not done?
Ye Fan rode this underwater submarine and cruised all the way to the underwater base in the South China Sea. At this time, because it was already night, the bottom of the sea was already out of reach.
Except for some deep-sea fish with their own light sources, which look like fireflies in the dark, the deep sea is completely silent.
The strange shapes, all kinds of fish, and some underwater creatures that looked like celestial beings constantly refreshed Ye Fan's worldview at the beginning.
Under the guidance of Origin, Ye Fan stepped out of the submarine, started the ion engine, and flew to the sea tunnel, intending to return directly to Datang Heavy Industry to end the day's fatigue.
In any case, after Datang Heavy Industry has invested 100 billion in upgrading and transformation, its equipment and industrial base machines have also begun to be upgraded.
Whether it is the production of steel armor ~EbookFREE.me~ or the production of liquid metal, or the production of holographic projection modules, it is constantly increasing.
At the same time, many locations have been reserved to facilitate other technologies and other equipment to be put into production.
Nowadays, 100 billion yuan of funds has only been spent less than 7 billion yuan on transformation, and there have been such fruitful results. If all the 100 billion yuan is smashed, what will Datang Heavy Industries look like?
This also aroused Ye Fan's curiosity.
Now what Ye Fan needs is time, just a word, wait.
...
On the other side of the ocean, the Supreme Command of Amegian.
A white man hit the table with a punch.
"Fak! How could they be in the Bermuda Triangle! How could they sink suddenly! Check it out for me! Be sure to check it out!" The commander said with a look of dark bird, very angry.
