Xueba's Black Technology Simulator

Chapter 50 Everything is ready, only the east wind is owed (for further reading)

The sonar equipment brought over this time is a small sonar, and the receiving and transmitting are connected together with external lines.

And in appearance, the ultrasonic emitting device is a sphere, and the receiving device is a rotatable arc shape similar to the ground pot-shaped radar.

On submarines, sonar is generally installed on the head or tail.

Some aircraft also have sonar radars. For example, the Sun Never Sets has two aircrafts. The Falcon AWACS and the Hunter AWACS have radars integrated into their fuselages.

There is a ball on the head directly in front of the plane, and there is a "big plate machine", the middle part of the plane is a disc.

Lu Xiao connected the data cable to the ultrasonic receiving device, and Wang Meng also started the generator on the other side to supply power to the instrument.

Now it is in the testing stage, you can just aim at any direction and emit ultrasonic waves.

Lu Xiao turned on the instrument facing the mountain in front of him.

There are still many people watching around, all of whom are the commanders of the official search and rescue team and the blue sky rescue team.

When they saw Lu Xiao playing with computers and instruments, they thought Lu Xiao was an ordinary staff member responsible for operating the equipment.

However, Peng Fangcun's attitude quickly made everyone feel that Lu Xiao was not simple.

"How about Lu Xiao, can you use it?" Peng Fangcun asked.

"Well, it's no problem to use it, but to cover so many mountains, we need to choose a good angle. Unless we can go to the highest mountain top, the search range is limited." Lu Xiao said.

The instrument starts and the ultrasound is excited.

Lu Xiao's ears immediately heard the ultra-high-frequency sound waves, and he was sure that no one else could hear them.

It's a pity that his brain is not programmed, and there is no imaging modeling software, so naturally he cannot recognize what the information is.

If you want your brain to be like a computer, you must at least program your brain and install useful software.

Or program the genes to learn from bats.

Create a special organ to specifically recognize ultrasound.

This is temporarily impossible. The working principle of brain neurons is different from that of diodes, and Lu Xiao has no way to control the work of neurons. Instead, it is possible to study external chips in the brain in the future to indirectly realize the function of transforming ultrasound imaging at any time.

Lu Xiao focused all his attention on the computer. His computer was just a slightly high-end Alien brand computer.

Barely able to process part of the data.

According to the performance of the computer, Lu Xiao has made restrictions on the software level.

The current sonar devices in the world, such as the currently leading AN/BQR-2B passive detection sonar in Eagle Country, can detect ship types at 130 kilometers to 160 kilometers, while active detection sonar such as AN/BQS-4 has higher accuracy. , but the maximum detection distance is less than 20 kilometers.

These sonar devices are enormous.

In addition, there is the latest synthetic aperture sonar, which is actually somewhat similar to Lu Xiao's current technology.

Using synthetic aperture sonar detection, it can detect 400 meters away with a resolution of 10CM.

If we use the data of synthetic aperture sonar and add Lu Xiao's software, the resolution can be at least centimeter or even millimeter level.

The farther it is from the receiving device, the more blurred the data will be. In theory, Lu Xiao's current device can detect within 1-3 kilometers, and it will be clearer within 500 meters. If it is farther away, his computer will not be able to withstand it.

500 meters is not enough for Daxueshan search and rescue.

Lu Xiao said to Peng Fangcun while operating the software: "If there is no problem with my test later, I have to send a helicopter over immediately, and put the equipment on the helicopter to scan and model all the mountains in all directions. Peng Lao can call the helicopter Bar?"

Before Mr. Peng could speak, Zhang Bing asked in confusion, "But the noise on the helicopter is so loud?"

Peng Fangcun rolled his eyes. He has a lot of contact with Lu Xiao, and he roughly knows the principle of the software. He reminded: "Can the noise you can hear be the same as the ultrasonic wave? The frequency is different, and there will be no interference between them. By setting the parameters in the software, the noise of the helicopter can be erased.”

"Oh oh oh, I was thinking about it." Zhang Bing nodded quickly.

He's a combat drone expert, not a radar expert...

Peng Fangcun thought for a while and picked up the phone to call an old friend in Southwest District J. His work will contact people in various districts.

Just so happens to have friends in the Southwest too.

"Old Fan, I, Peng Fangcun, want to ask you for a favor. I am currently conducting the latest radar test in the Daxue Peak area of ​​Xiling Snow Mountain. Someone is lost in the snow mountain here. Can you send a helicopter to cooperate with the work?" Peng Fangcun said quickly.

Lao Lin is from Southwest District J, knowing that Peng Fangcun actually came to their protected area to do the latest radar test.

Suddenly, it seemed like a cat smelled meat, and immediately said it was okay.

It can arrive in half an hour at the fastest.

He will also come over in person, good things can't be missed in Southwest this time!If he hadn't been thick-skinned, Peng Fangcun probably wouldn't have thought about Southwest District J at all.

You must know that this place was originally around Rongcheng, Sichuan Province. At first, Lu Xiao arrived at Xiling Snow Mountain after only 1.5 hours driving from the urban area.

And people who live in Rongcheng, especially those who live in New District D, can often see helicopters buzzing overhead.

The people of Rongcheng are actually very lucky. In addition to being able to see helicopters, they can occasionally hear the sonic boom of J-20 fighters.

This is a situation that is difficult for many people to experience.

When the members of the search and rescue team saw that Peng Fangcun had made a phone call, they even found a helicopter, and they were immediately overwhelmed with admiration.

Of course they could also find a rescue helicopter, but the search and rescue helicopter was naturally different from the one Peng Fangcun was looking for.

Search and rescue helicopters dare not fly in bad weather.

The performance of the two helicopters is different, and of course the pilot skills must also be different.

Lu Xiao was able to direct Peng Fangcun to work, which also surprised everyone.

Soon Lu Xiao received countless feedback data, and his laptop worth more than 2 yuan also started working.

The 3D automatic modeling software designed separately, is modeling.

Before that, Lu Xiao had already intercepted part of the data, eliminated the interference of ordinary tree sound wave information, and kept only the terrain and the people in the terrain.

After a few minutes, the 3D software will model the range of 500 meters in the corresponding direction of the receiver in three-dimensional space.

Even people like Lu Xiao who are in the command tent are no exception!
Even they are the clearest, as long as you zoom in on the [-]D model, you can see everyone's appearance clearly.

Of course, because there is no special processing, all graphics are black and white, and the grayscale is not obvious, so it is basically impossible to see what it is.

Lu Xiao operated again, and soon let the software AI program automatically adjust the gray scale of the model, with light and dark changes.

Everyone can see a map scene appear on the laptop screen!
A member of the Blue Sky Search Team out looking for someone.

A dozen people staying in the tent.

The car not far away, the boulder on the mountain.

All on the computer screen, clearly displayed.

"This, it can remove all the trees! It's amazing!" Someone couldn't help exclaiming.

He simply couldn't understand what kind of technology it was.

Why are trees and even tent tarpaulins not interfering with the picture in any way.

In fact, Lu Xiao can only display humanoid creatures, and then the rest of the screen will be dark, and the places with people will be white.

Just adjust it, and you can see what everyone looks like, where they stand, whether they are lying down or lying down or walking.

Because it is 3D modeling, Lu Xiao can walk around the human model to see what it looks like.

But this time it won't work. To model a clear human face, more data needs to be absorbed, and a helicopter with sonar equipment must collect a large circle of data.

Now it is data in one direction, just like a flashlight shines in one direction and is blocked by a wooden board.

We can know what one side of the board looks like, and the software will automatically generate the entire model, but on the back side, it is actually incomplete data.

But if the detector is in the sky, it will always output ultrasonic waves and receive echoes.

A large amount of data will be generated, and these data will piece together a model that is the same as reality, and the automatic modeling accuracy is very high.

Next, Lu Xiao first connected to the National Supercomputing Center, and uploaded the software encrypted with the permission given by Peng Fang.

His laptop serves as a terminal for receiving information, and all calculations are performed by supercomputers.

All is ready except for the opportunity!
As soon as the helicopter arrives, Lu Xiao can show his skills.

After preliminary testing, the sonar imaging system is perfect.

And all of this was also captured by the bodyguard Wang Meng with a video camera, which will be used as video material for Lu Xiao's B station in the future.

ps: I'm on the list on Monday, and I'm asking for a small tip. Is there anyone who can support me a little bit.Ranked 12th is only 2 places away from the top ten.
