This civilization is very strong, but the technology tree is a bit crooked

Although for some aircraft with stealth design, radar often fails to detect and cannot detect the signals of these aircraft.

But in this case, it is just a routine scan of the radar, which is equivalent to a hasty glance.

Whether it is the scanning angle, scanning frequency, or scanning power, none of them are turned to the maximum, and there is no targeted detection.

The target is also to enter the village quietly, don't shoot, and try to hide your signal as much as possible.

but.

If the radar ignores the loss and the impact on various surrounding signals.

Switch the angle and frequency several times, and increase the scanning power of the radar at the same time.

With the violent performance of the land-based radar, the B2 stealth bomber came in, no matter how quietly it entered the village, without shooting or shouting, trying to hide its signal and figure, it was impossible to escape the detection of the land-based radar.

However, now.

The positioning signal of Chen Yi's drone was clearly in front of him.

Altitude, speed, direction, flight angle and other parameters are all available.

Land-based radars everywhere are still like blind people.

No matter how you switch angles and frequencies, you can't find the trace of Chen Yi's drone.

You know, the blind man feels the elephant.

It can be found out whether it is a pillar, a fan, or a wall.

But now, told that there is a drone in this location.

These advanced radars, which claim that no sparrow can escape detection at an altitude of 10,000 meters, have become blind one by one, and not even a single hair can be seen.

"submit application."

"Request increased power for detection!"

After careful tracking and detection for more than half an hour, Chen Yi's drone was still not found.

The person in charge of the management center, after thinking for a moment, decided to request the application to increase the radar power.

It is not a trivial matter to increase the power of the radar.

Except for emergency situations where special intelligence and suspicious signals are found, or when preparing for war, the power can be increased first, and the report can be written afterwards.

Usually, if you want to increase the radar power, you must go through some application procedures.

It took a while to submit the application.

Approved above.

The person in charge looked at the approved application form and picked up the phone.

Called the local air traffic control bureau and the operator.

Three minutes after the announcement, a special drill will be launched to prepare for signal interference.

"Start the first-level plan, increase the power of the radar to the maximum, and detect the traces of the locked target!"

"yes."

Three minutes flew by.

With the order issued, the local ground-based radars were activated at full power one by one.

The electromagnetic waves emitted by the radar have suddenly increased by a hundred or even hundreds of times.

According to the location information, Furiously aimed at the position of Chen Yi's drone in an orderly manner.

Zizizi!

Guangxi Province, Yunnan Province, Sichuan Province, and even the surrounding areas of these areas.

In addition to wired signals, other wireless mobile phone signals, radio stations.

At this moment, everything was disturbed, and the signal suddenly became extremely poor.

Unsteady calls, abnormal calls, and even call interruptions began to appear.

In addition to Beidou positioning.

Other positioning systems such as GPS completely lost their signal at this moment.

"Report, the radar in Area 1 is in the positioning signal area, and no target signal has been found!"

"Report, the radar in Area 2 is in the positioning signal area, and no target signal has been found!"

"Report, the radar in area 3 is in the positioning signal area, and no target signal has been found"

A few minutes passed.

Switch the frequency, angle, and power up multiple times, and conduct several rounds of all-round detection.

The radar operators in charge of controlling the radar reported back the detection situation, but none of them found Chen Yi's drone.

At this moment, the person in charge of the command center was stunned.

"Is there a problem with the positioning chip because I didn't fly the drone?"

A ridiculous idea came to the person in charge.

But looking at the screen display, it is moving at supersonic speed.

Sometimes it goes up, sometimes it goes down, and sometimes it turns around.

Just look at the signal trace that you know you are having fun.

No matter how you look at it, this doesn't seem like a problem with the positioning chip.

Think about it.

The person in charge picked up the confidential phone on the table and dialed a number.

"Number 0A01, applied for a drone test flight today."

"Where did you fly?"

The phone was stunned for a moment, and the voice suddenly raised: "Go to the moon, or fly to Mars?"

"."

The person in charge was also speechless by this reaction, shook his head and said, "No, I just went shopping at home.

Apply for the airspace below 70,000 meters, all the way to the west of Penghai.

What to say to catch up with the day, go to Mount Everest to punch a card. "

"Oh, it's better not to go to Mars."

On the other side of the phone, he breathed a sigh of relief: "It's good to play at home.

As long as it doesn't interfere with the flight of civil aviation airliners, flying at home is better than flying to an alien planet.

It seems that the trip to Rongfei in the past, after being taught by a group of academicians and experts, still has some effect. "

The person in charge rubbed his forehead: "But there is a problem with this test flight, that is, the radar cannot detect the trace of the drone."

"Isn't that normal.

He has studied the Black Hawk for more than 20 days, and it is normal to learn stealth design.

According to the small and exquisite size of the UAV, coupled with the stealth design, it is normal that the radar in the conventional mode cannot detect it. "

It is normal to learn the stealth design of the aircraft in more than 20 days.

What kind of normal is this.

The person in charge was completely speechless: "It's not a regular model.

I just applied for radar full-power detection, and tracked the coordinates of the positioning signal of the drone, but I still didn't find it. "

"hiss!"

On the other side of the phone, I was shocked: "Land-based radar?"

"Ground-based radar."

"Doppler pulse, phased array radar, all types of radar are activated?"

"It's all started."

".This pervert!"

There was a sudden swearing on the phone. After a moment of silence, he asked, "Where is 0A01 now?"

"Let me see."

The person in charge looked at the screen next to him: "The current signal location is in the canyons of the Hengduan Mountains.

The signal didn't move much.

But the altitude is constantly diving and rising.

This...should be surfing.

Aerial Drone Surfing”

"Whooooooooooooooooooooooooh!"

Penghai City, the open balcony on the third floor.

Chen Yi was wearing a virtual helmet and was yelling provocatively.

In the virtual helmet, the drone's first perspective is displayed.

With infrared scanning on, the uninhabited canyons in the Hengduan Mountains were constantly diving up and down.

Every time it is pulled up, the drone will cross a canyon.

Then came to an altitude of several thousand meters and turned the nose.

Aim for the next canyon, a nearly straight dive sprint.

Every sprint.

The virtual program simulates the feeling of complete weightlessness, the rapidly enlarged peaks on both sides, the river in the canyon, and the whistling wind captured by the microphone.

Through brain wave virtualization, it clearly appeared in Chen Yi's mind from the first perspective.

Reaching the bottom of the valley, turning the direction and pulling up, the fuselage creaked due to overload, and it seemed that it would be torn apart at any time, which made people feel adrenaline boiling.

"Those roller coasters, jumping machines, big pendulums, traversing machines and so on, how can it be as cool as surfing directly in the canyon."

"It seems that virtual technology combined with drone flight is the real kingly way."

"Other hand flying, rudders, and even AR glasses are all wrong!"

Played for half an hour.

Chen Yi took off the virtual helmet contentedly.

Raise the drone and leave the canyons of the Hengduan Mountains.

Leave the canyon and come to an altitude of 20,000 meters.

Chen Yi pulled out the flight data of the drone to check the test flight situation on the way from Gui Province.

Especially the extreme working conditions of the canyon sprint just now, the performance data of the drone.

But the flight data just pulled out.

When Chen Yi saw it, he immediately discovered an unusual problem.

That is, it cannot be directly exposed to sunlight.

The bottom solar cell film, which can only be charged by air diffuse reflection, has abnormal charging.

"strangeness?

Why is there a period of time.

The solar battery film on the bottom of the drone has increased the charging efficiency by more than 50% at once.”

Just when Chen Yi was wondering.

The phone next to him ding-dong.

One is about the three major regions of Guangxi, Yunnan and Sichuan.

Because of the electronic warfare exercise, news that all mobile phone signals were abnormal popped up.

Seeing the news, Chen Yi suddenly realized.

"So that's it. Thanks to Radar, the energy you sent!"

PS: I chatted with the editor today and asked if Sanjiang had any hope, and got a word, hang!

woo woo woo...
