Cyber Heroes

In the early days when the radar technology was just born, clouds, fog, rain, and haze would cause certain echo interference to the radar. The electromagnetic waves emitted by the radar will be reflected, absorbed or scattered by these things, causing the results to be unstable.

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

By the 21st century, except for a small number of weather radars that specifically limit electromagnetic waves to specific bands, most radars will not be interfered by clouds and fog.

However, the essence of fog is an aerosol of water particles using air as a dispersant. If this particle is replaced by a metal sheet, then things will be different.

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

A cloud of less dense aerosol may not be much different from a small flying object in the field of view of microwave radar.

And this kind of moving object that has not passed the identification of friend or foe is very likely to be judged as an enemy by automatic weapons, and then fire autonomously.

This is a complete waste of ammunition facing the air, and will expose its own layout in advance.

Balbo immediately closed his eyes and ordered the entire unit to disconnect the microwave radar from the fire control system and connect it to the sonar radar.

Most tanks are equipped with both functions.

However, Balbo soon opened his eyes angrily, and an angry red light burst out from the prosthetic eyes [this is the built-in emotional expression mechanism of the prosthetic eyes]

Communication barriers.

This time, Tiehua is not a dense mass like the conventional one, but is scattered over a wide area, so it cannot perfectly isolate all communications and active exploration based on electromagnetic waves like normal. In this situation, communication can still be used from time to time, and active detection can only easily detect false targets.

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

But for large corps, this would cause serious disruption to the chain of command.

Before Balbo could make any further reaction, sporadic gunfire came from the front. There is also a little bit of fire.

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

The communication failure ahead was reported ten minutes ago. It was just that the technical team was investigating other matters at that time. The technical officer stood at attention and said: Since we triggered an EMP mine half an hour ago, some people suspect that maybe that But I found that the scope of this communication barrier showed a spreading trend, and the spreading speed was 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 internal system of the Gene Bank Arms. Soldier, you will get better treatment when you go back. Forward the information to me.

Yes! The technical officer was ecstatic and immediately transferred his previous statistical results.

Balbo looked at the scope of the communication failure and the subsequent data. With a change of thought, he downloaded more accurate data from various nearby weather monitoring stations and weather satellites in the sky. It's just that the download speed is very unstable, jumping between a few hundred bits to several GB at any time.

The range is very large. Balbo thought: If you want to reach a density that can cause communication barriers, but also ensure that it is invisible to the naked eye, it would require dozens of tons of iron and steel.

Dozens of tons... How is this possible? Ordinary Jianghu people only carry a few groups, which is a hundred kilograms. The regular reserves of Green Forest Village are only a few tons at most. And that is a long-term reserve for hundreds of people.

What exactly is happening ahead?

The person who should be most suspicious should be the target they are tracking, the knight who assassinated the deputy leader of the Mana Knights. He should be one of the few people who consciously spreads Tiehua.

However, this is a little hard to believe.

Wide-area low-density Tiehua is actually a very old tactic. But the problem with this tactic is that it's so old.

This tactic was born before the Ascension War. At that time, the global logistics system, financial system and information network were highly integrated. An experienced hacker can hide himself, parasitize in this huge system, steal resources continuously, weaken the enemy and strengthen himself at the same time.

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 isolated from the patron's logistics system.

Even if a master of internal energy has great abilities, 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 senior cadres of the gene bank armed forces, and most of them are placed inside giant buildings.

Even if there really is a batch of resources in the corner of the warehouse that have been wiped out by internal masters from the past and the future, the knights cannot get them.

Preparing dozens of tons of iron flower was not that difficult for knights in the past, but it is not that simple now.

There might be a Green Forest Village right ahead? After that knight rushed into the Green Forest Village, he destroyed all the Green Forests, and then took all the metal reserves and energy reserves of the Green Forest Village to produce Tiehua.

If you don't consider the service life of the 3D printer, it's really too late to prepare.

The 3D printer can produce Tiehua very quickly. A small amount of powder is sprayed on the bottom plate, and the shape is assisted by a magnetic field. The crystal is formed using sound wave interference, and the laser heats it instantly.

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

He looked it up. There is indeed an area directly ahead that is suspected to be occupied by the Sandstorm Ghost, a green forest force. Their stronghold is probably there.

A bit troublesome. The government had no previous plan to clear up the ghosts of sandstorms. So the scope of suspicion marked on the map is a bit wide. Applying to use Heavenly Punishment on such a large area will not only waste ammunition, but also hinder the march of the troops.

If the tactics are not handled properly, the real target may be able to escape just like that.

While he was thinking, a line of fire suddenly appeared on the edge of the horizon.

Then, there was a flash of light in the sky, like a few stars. After a few seconds, there was a muffled thunder.

This is... Balbo almost cursed: Who shot out the medium and short-range multi-warhead missiles! This is used to deal with fighter jets.

…………………………………………………………………………

With the help of the flash, Xiangshan could clearly see the surrounding troop divisions.

He threw out the remaining foil airplanes one by one.

It’s really not his fault. In the early years, Xiang Shan and a group of friends threw paper airplanes in a wind tunnel in the Russian Federation. His understanding of paper airplanes was really hard to come by.

These foil planes prioritize flying further - after all, the environment this time is different from the previous one, and there is no continuous updraft caused by the high temperature left by the explosion. These paper airplanes did not take radar reflection cross-section into account.

But this time Xiangshan didn't just do it on the spur of the moment.

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 the Longbo lens, a spherical multi-faceted refractive lens that can form two mutually refracted and infinitely magnified images on both sides of the lens.

To put it simply, this thing shines like gold in the eyes of radar.

In the past, if stealth fighters wanted to participate in air shows, military parades, training and other activities, they had to be detected by radar so that ground crews could plan and manage them. However, the problem with many stealth fighters is that their stealth performance is so good that even if the route is known in advance, it is difficult for radar to lock on it.

At this time, the stealth fighter will attach an external Longbo lens to amplify its own signal to ensure that it is observed by its own radar.

When the paper plane flew over with this thing, in the observation of those radars, it was equivalent to a medium-sized drone, small tank or warrior rushing over.

Nature will inspire a reaction.

It seems that the density of troops is indeed not very high and within the acceptable range. Thank you to those broadcasters. They did do something very meaningful.

Xiangshan is constantly simulating the movement of metal aerosol clumps in his mind. He released the temporarily sensed wind direction and wind speed detection instruments and had been calculating for a long time. At the same time, he dropped all the metal aerosol sustained-release bombs. He knows all the initial values.

It is true that long-term accurate simulation is not possible, but short-term simulation is possible.

In some areas, aerosol clumps were hit, but no fire was heard. But it stands to reason that the search network would not have such a big flaw. This shows that there are troops in this area, and they have already moved the microwave The radar was separated from the fire control system.

But not every unit has received the order.

Possibility one is that one of their teams discovered the aerosol and reported it. Possibility two is that the intermediate command system discovered the aerosol and then issued an order.

The troops that were still firing at the aerosol clumps after the 'order was issued' temporarily cut off communication with the command center. At that point in time, there must be a large aerosol gap between them and the command center. Sol clumps.”

So, where the command center may be...

A large area appeared in Xiangshan's mind. And these areas are constantly shrinking... shrinking...

Then, there was a firefight in an area not far in front of Xiangshan.

Xiangshan lowered his body.

here we go.
