Chapter 208 Back to the Carbine

In the early days when the "radar" technology was just born, clouds, fog, rain, and haze would all cause certain echo interference to 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, and the electromagnetic waves it emits are often limited to a very narrow frequency band, and the noise floor of interference can be filtered out through modulation technology.

In 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 with air as a dispersant.If this "particle" is replaced by a metal flake, 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 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 independently.

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

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

Most tanks are equipped with both functions.

However, Balbo quickly opened his eyes angrily, and a red light of "anger" shot out from 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 mass like the usual ones, but spread over a wide area, so it can't perfectly isolate all electromagnetic wave-based communications and active detection as normal.In this case, communication still works from time to time, and active detection is only easy to detect false targets.

In addition, because the density of Tiehua is too low, it does not have the ability to cause a short circuit in an instant, and it cannot be ignited.

But for a large legion, this will cause serious disruption to the chain of command.

Before Balbo could react further, sporadic gunfire came from ahead.Plus a little fire.

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

"The communication barrier ahead was reported 10 minutes ago. It's just that the technical team was investigating other content at that time." The technical officer stood up and said: "Because we triggered an EMP mine half an hour ago, some people suspect that maybe that However, I found that the scope of this communication barrier showed a tendency to spread, and the spread speed was positively correlated with the wind speed, so I made an electromagnet and tried it.”

Balbo nodded: "You have done a good job. The commendation order has been uploaded to the internal system of the gene pool arm. Soldier, you will get better treatment when you go back. Pass the information to me."

"Yes!" The technical officer was ecstatic, and immediately adjusted his previous statistical results.

Balbo looked at the scope of the communication barrier and the subsequent data. As soon as he changed his mind, 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." Balbos thought: "If it is to achieve a density that can cause communication barriers, but also guarantee a state that the naked eye refuses to see, then dozens of tons of Tie Hua are needed."

"Dozens of tons...how is this possible? Ordinary Jianghu people only bring a few groups, which is no more than a hundred kilograms. The regular reserves of the Green Forest Village are at most a few tons. And it is a long-term reserve for hundreds of people."

"What the hell is going on ahead?"

The person who should be most suspicious should be the target of their pursuit, the knight who assassinated the deputy head of the Mana Knights.He should be one of the few people who consciously spread Tiehua.

However, this is a little bit hard to believe.

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

This tactic was born before the War of Ascension.In that era, 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 endlessly, 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 precautions against knights.Most knights are also physically isolated from the Asylum's logistics system.

Even if a master of inner strength is capable of hiding a batch of goods and sending them to the wrong area, there is no way to really receive the goods.All the nodes of the logistics system—the large warehouses—are all under the management of senior cadres of the gene pool armed forces, and most of them are placed inside giant buildings.

Even if there are really a group of resources in the corner of the warehouse that have been erased by the masters of the inner family, the knights will not be able to get them.

"Preparing dozens of tons of Tiehua" was not so difficult for knights in the past, but it is not so simple now.

"Maybe there is a green forest village right in front? After the knight rushed into the green forest village, he wiped out 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."

3D printers make Tiehua very fast.A little powder is sprayed on the bottom plate, and the shape is assisted by a magnetic field, and the crystal is formed by the interference of the sound wave, and the laser is heated instantly.

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 looked it up.There is indeed an area directly in front of it that is suspected to be occupied by the "ghost of the sandstorm" of the green forest force.Their Dazhai is very likely to be there.

It's a little troublesome.The government did not have a plan to clear the "sandstorm ghosts" before.So the "range of suspicion" marked on the map is a bit large.Applying to use Heaven's Punishment on such a large area would not only waste ammunition, but also hinder the troops from marching.

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

While he was thinking, a line of fire suddenly rose from the edge of the horizon.

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

"This is..." Balbo almost cursed: "Who shot out the medium-range and short-range multi-warhead missiles! This is for dealing with fighter planes."

..............................................................................

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

He also threw out the remaining tinsel planes one by one.

It's really not him blowing.In the early years, Xiang Shan and a group of friends threw paper airplanes in the wind tunnel of the Russian Federation for fun. His understanding of paper airplanes is really not good.

These metal-foil planes give priority to "flying farther" - after all, the environment this time is different from that of the show, and there is no continuous updraft caused by the residual high temperature of the explosion.These paper planes don't take much into account the radar cross section.

But this time Xiang Shan didn't do it on a whim.

All the paper airplanes trailed a bullet-reflecting spherical object like a tiny glass bead.

This thing is called "Longbo lens", a spherical multi-faceted refracting lens, which can form two mutually refracted and infinitely magnified images on both sides of the lens.

To put it simply, this thing can be described as a golden light in the eyes of the radar.

In the past, if stealth fighters wanted to participate in activities such as air shows, military parades, and training, 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.

At this time, the stealth fighter will mount a Longbo lens to amplify its own signal, so as to ensure that it can be observed by its own radar.

And the paper plane flew over with this thing, and in those radar observations, it was roughly equivalent to a medium-sized drone, small tank or warrior rushing over.

Nature is what sparks a reaction.

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

Xiang Shan's mind is always simulating the movement process of the metal aerosol clumps.He released the wind direction and wind speed detection instruments he had sensed temporarily, and had already calculated for a long time.At the same time, he dropped all the metal aerosol slow-release bombs.He knows all initial values.

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

"In some areas, aerosol clumps were hit, but no fire was heard. But logically speaking, the search net would not have such a big hole. This shows that there are troops in this area, and they have put the microwave The radar was separated from the fire control system."

"But not every unit has received orders."

"Possibility one, one of their teams discovered the aerosol, and then reported it. Possibility two, the middle-level command system discovered the aerosol, and then issued an order."

"The troops that still fired at the aerosol clumps after the time point of 'give orders' have temporarily lost communication with the command center. At that time point, there must be a large air gap between them and the command center." Sol clumps."

"Then, where the command center might be..."

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

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

Xiangshan lowered his body.

it has started.
