Cyber Heroes

In the early days of the "radar" technology, clouds, fog, rain, and haze all caused some echo interference to the radar. The electromagnetic waves emitted by the radar will be reflected, absorbed or scattered by these things, resulting in unstable results.

However, with the advancement of technology, radar is becoming more and more accurate. The electromagnetic waves it emits are often limited to a very narrow frequency band, and the interference noise can be filtered out through modulation technology.

In the 21st century, with the exception of a small number of weather radars that specifically limit electromagnetic waves to specific bands, overwhelming majority radars will not be interfered by clouds and fog.

However, the essence of "fog" is an aerosol of water particles with air as a dispersant. If this "particle" is replaced with a metal flake, then things will be different again.

The frequency band of electromagnetic waves that water molecules can absorb and reflect is quite limited, but metal can interfere with overwhelming majority electromagnetic waves.

An aerosol that is not too dense may not be much different from a small flying object in the field of view of a microwave radar.

And this kind of moving object that has not been identified by the friend or foe is very likely to be judged as an "enemy" by the automatic weapon, and then fires spontaneously.

This is completely a waste of ammunition against the air, and it will expose its layout in advance.

Balbo immediately closed his eyes and ordered the troops to separate the microwave radar from the fire control system and connect to the sonar radar instead.

Most war chariots are equipped with these two functions at the same time.

However, Balbo quickly opened his eyes angrily, and "angry" red light burst into the prosthetic eye [This is the built-in emotional expression mechanism of the prosthetic eye]

Communication barriers.

This time, the Tiehua is not a dense block like the conventional one, but scattered in a wide area, so it can’t perfectly isolate all based on Communication and active detection of electromagnetic waves. In this situation, communication is still available from time to time, and active detection is only easy to detect false targets.

In addition, because the density of iron flower is too low, it does not have the ability to cause a short circuit instantly, let alone ignite.

But for a large Legion, this will cause serious interference to the command system.

Without waiting for Balbo's further reaction, sporadic gunfire was heard in front of him. There is also a bit of light.

"It's late..." Balbo turned to the technical officer: "When did you find this?"

"If there is a communication barrier ahead, it was in ten minutes. The report was made before. It was just that the technical team was investigating other content at the time." The technical officer stood at attention: "Because we triggered an EMP mine half an hour ago, some people suspected that it might have an impact. But I found this communication barrier. The range shows a trend of diffusion, and the diffusion speed is positively correlated with the wind speed, so I made an electromagnet and tried it."

Balbo nodded: "You did a good job. The commendation order has been uploaded to the genes. The internal system of the library armed forces is now. Soldiers, you can get better treatment when you go back. Pass the information to me."

"Yes!" The technical officer was ecstatic and immediately changed his previous The statistics have been adjusted.

Balbo looked at the range of communication obstacles and the subsequent data. As soon as his thoughts turned, he downloaded more accurate data from various nearby weather monitoring stations and weather satellites in the sky. But the download speed is very unstable, beating between a few hundred bits to a few GB at any time.

"The range is very large." Balbo thought: "If you want to achieve a density that can cause communication barriers, but still ensure that the naked eye will not be able to see it, it will take dozens of tons of iron flower. "

"Dozens of tons...How is this possible? Ordinary Jianghu people also bring a few groups, not a hundred kilograms. The regular reserve of the Green Forest Cottage is only a few tons at most. And that is still for hundreds of people. Long-term reserve for use."

"What happened ahead?"

The most suspected object should be the target they were tracking, the one that assassinated the Knight Commander Your lord's knight. He should be one of the few people who consciously spread Tiehua.

However, this is slightly unbelievable.

"Wide-area low-density iron China" is actually a very old tactic. But the problem with this tactic is that it is really Immemorial old.

This tactic was born before the battle of sublimation. In that era, the global logistics system, financial system and information network were highly integrated. An experienced hacker can hide himself and become parasitic in this huge system, stealing resources endlessly, weakening the enemy while strengthening himself.

Now, the difficulty of doing so has been infinitely increased. The asylum management system has more preventive measures against knights. Most knights are also physically cut off from the logistics system of the asylum.

Even if Heavenspan, an internal strength expert, hides a batch of goods and sends it to the wrong area, there is no way to actually receive the goods. All nodes of the logistics system-large warehouses, are all under the management of high-level cadres of the gene bank armed forces, and are mostly placed inside huge buildings.

Even if there is a batch of resources that have been erased from the past and the future by the Inner sect expert in the corner of the warehouse, the knights cannot get it.

"Preparing dozens of tons of iron flowers" in the past was not so difficult for the knight, but now it is not so easy.

"up ahead there might be a green forest Dazhai? After the knight rushed into the green forest Dazhai, he destroyed all the green forests, and then took all the metal reserves and energy reserves of the green forest Dazhai to produce Tiehua."

"If you don't consider the use of lifespan for 3D printers, you really have time to prepare."

The speed of 3D printer manufacturing Tiehua is very fast. A small amount of powder is sprayed on the bottom plate, and the shape is assisted by a magnetic field. The crystal is formed by the interference of sound waves, and the laser is instantly heated.

If a green forest Dazhai does not consider metal reserves at all, it can indeed produce a lot in a short period of time.

He checked. up ahead There is indeed an area that is suspected to be the area occupied by the "sandstorm ghosts" of the green forest forces. Their Dazhai is likely to be there.

A little troublesome. The government had no plan to clear the "sandstorm ghost" before. So the "scope of suspicion" marked on the map is a bit large. If you apply for the use of heavenly punishment in such a large area, not to mention wasting ammunition, it will also hinder the march of troops.

If the tactics are handled improperly, the real target may escape like this.

As he was thinking, a line of fire suddenly rose on the edge of the horizon.

After that, there was a flash of light on the horizon, like a few stars. A few seconds later, a muffled thunder sounded.

"This is..." Balbo almost scolded: "Who shot the mid- and short-range multi-warhead missiles! This is for combat aircraft."

………………………………………………………………

With the help of the flash, Xiang Shan can see the surrounding troops clearly.

He threw out the metal foil paper airplane left on his hand one after another.

It's really not him. In the early years, Xiang Shan and a group of friends were throwing paper airplanes in the wind tunnels of the Russian Federation. The understanding of paper airplanes was really unbelievable.

These metal foil paper airplanes give priority to "flying farther"-after all, the environment this time is different from the scene, there is no continuous updraft caused by the high temperature of the explosion residue. These paper airplanes did not consider the radar reflection cross section.

However, this time Xiang Shan was not on a temporary basis.

The front end of all paper airplanes drags a spherical object with a bullet reflecting surface, like a small glass bead.

This thing is called "Longbo lens", a spherical multi-faceted refractive lens that can form two images that refract each other and infinitely magnify on both sides of the lens.

To put it simply, this thing is shining golden light in the eyes of the radar.

In the past, if the stealth fighter wants to participate in activities such as airshows, military parades, training, etc., it must be detected by radar so that the ground crew can plan and manage it. However, the problem with many stealth fighters is that its stealth performance is really very good. Even if the route is known in advance, the radar is difficult to lock.

At this time, the stealth fighter will attach a Longbo lens externally to amplify its own signal and ensure that it can be seen by the radar.

And the paper airplane flew over with this thing, in those radar observations, it was roughly equivalent to a medium-sized drone, a small war chariot or a Martial Artist rushing over.

Naturally it will stimulate a reaction.

"It seems that the density of the troops is indeed not very high, within an acceptable range. Thanks to those broadcasters. They did a very meaningful thing."

Xiang Shan's mind is constantly simulating the movement of metal aerosol clumps. He released the temporarily sensed wind direction and wind speed detection equipment, which has been calculated for a long time. At the same time, all the metal aerosol slow-release bombs were released by him. He knows all the initial values.

It is true that long-term accurate simulation cannot be done, but short-term simulation is possible.

"Some areas hit aerosol clumps, but no fire was heard. But logically speaking, the search network would not have such a large weak spot. This shows that this area There are troops, and they have separated the microwave radar from the fire control system."

"But not every force has received instructions."

"probability one, they One of the squad found aerosols, and then reported them. Probability two, the intermediate command system found aerosols, and then ordered."

"The aerosol group is still reported to The unit that fired on the block temporarily disconnected the communication with the command center. At that point in time, there must be a larger aerosol mass between them and the command center."

"So, Where the command center is likely to be..."

A large area appeared in Xiang Shan's mind. And these areas have been shrinking...shrinking...

Then, there was a firefight in the area not far in front of Xiang Shan.

Xiang Shan lowered his body.

It's started.
