Although for some aircraft designed to be stealthy, the radar often fails to detect the signals of these aircraft.

But this situation is just a routine scan of the radar, which is equivalent to a quick skimming.

Whether it is the scanning angle, scanning frequency, or scanning power, all of them are not opened to the maximum, and there is no targeted detection.

The goal is also to quietly enter the village, do not shoot, and hide their signals as much as possible.

But.

If the radar ignores the loss, regardless of the impact on various signals in the surrounding area.

Switch the angle and frequency a few more times while increasing the scanning power of the radar.

With the furious performance of the land-based radar, the B2 stealth bomber came in, no matter how quietly it entered the village, did not shoot or shout, and tried to hide its own 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 is clearly placed in front of him.

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

Ground-based radars everywhere are still like blind people.

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

You know, the blind man touches the elephant.

You can tell if it's a pillar, a fan, or a wall.

But now, told that there was a drone at this location.

These advanced radars, which claim to have escaped detection by not a single sparrow at an altitude of 10,000 meters, have become blind one by one, and they can't see a single hair.

"Submit an application."

"Request a power boost for probing!"

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

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

Increasing the power of the radar is not a trivial matter.

In addition to the emergency situation of discovering special intelligence and detecting suspicious signals, or in combat preparation, you can increase the power first, and then write a report afterwards.

If you want to increase the power of the radar, you must go through some procedures to apply.

Not long after the application was submitted.

The above agreed to the application.

The person in charge looked at the application form that passed the trial and picked up the phone.

Calls were made to the local air traffic control authority and the operator.

Three minutes after the notification, a special drill will be carried out to prepare for signal interference.

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

"Yes."

Three minutes are fleeting.

As the command was issued, the local ground-based radars were activated one by one at full power.

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

According to the positioning information, the position of Chen Yi's drone was aimed at in a furious and orderly manner.

Zizizizi!

Gui Province, Yunnan Province, Sichuan Province, and even the periphery of these areas.

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

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

Calls are choppy, call is abnormal, or even the call is dropped.

And in addition to Beidou positioning.

Other GPS and other positioning systems have completely lost their signals at this moment.

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

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

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

A few minutes passed.

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

One by one, the radar personnel responsible for controlling the radar gave feedback on 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.

"Didn't you fly a drone, but there was a problem with the positioning chip?"

A ridiculous idea popped up in the minds of the person in charge.

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

Sometimes it goes up, sometimes it goes down, and every now and then there is a roundabout.

The signal trail that you can see having fun at a glance.

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

I thought about it.

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

"No. 0A01, I applied for a drone test flight today."

"Where did you fly?"

There was a flute on the other side of the phone, and his voice suddenly raised: "Landing on the moon, or flying to Mars?" ”

“......”

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

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

Say that you have to rush to the sun and go to Mount Everest to make a card. ”

"Oh, it's good that I didn't go to Mars."

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

As long as it does not interfere with the flight of civil airliners, flying at home is better than flying to aliens.

It seems that after a trip to Rong Fei in the past, after a group of academicians and experts taught by words and deeds, it still had 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 traces of the drone." ”

"Isn't that normal.

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

According to the small and delicate size of the drone, coupled with the stealth design, it is normal for the radar in the conventional mode to not be able to detect it. ”

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

This is normal for which door.

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 drone's positioning signal, but I still haven't found it. ”

"Shhh

On the other side of the phone, I was shocked all of a sudden: "Ground-based radar? ”

"Ground-based radar."

"Doppler pulses, phased array radars, all types of radars are activated?"

"It's all activated."

“...... This pervert! ”

There was a sudden burst of foul language on the other side of the phone, and after a pause, he asked, "Where is 0A01 now?" ”

"I'll see."

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

The signal didn't move much.

But the altitude is constantly swooping up.

This...... It should be surfing.

Surfing ...... of aerial drones"

......

"Woooooooooooo Ulla! ”

Penghai City, open balcony on the third floor.

Chen Yi was wearing a virtual helmet and was shouting excitedly.

In the virtual helmet, the first view of the drone is revealed.

Infrared scanning is on, and the uninhabited canyons of the Hengduan Mountains are constantly swooping up and down.

With each pull-up, the drone crosses a canyon.

And then to a height of several thousand meters, turn the nose of the plane.

Aim for the next canyon for a near-straight dive dash.

Every sprint.

The virtual program simulates the feeling of complete weightlessness, with mountain peaks amplified at great speed on either side, rivers with low canyons, and the sound of whistling wind captured by microphones.

Through the brainwave virtualization, it clearly emerged in Chen Yi's mind from the first perspective.

When you reach the valley and turn around and pull up, the crunch of the fuselage due to overload seems to be torn apart at any time, which makes people feel that the adrenaline is boiling.

"Those roller coasters, jumping machines, big pendulums, traversing machines or whatever, how can there be this direct surfing in the canyon."

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

"Everything else is flying with hands, what rudders, and even AR glasses are all evil!"

I played for most of the hour.

Chen Yi took off the virtual helmet with satisfaction.

Pull up 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 data of the drone's flight to check the test flight on the way from Gui Province.

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

But flight data just pulled out.

As soon as Chen Yi saw it, he immediately found an abnormal problem.

That is, you can't get direct sunlight.

The bottom solar film, which can only be charged by diffuse reflection of air, has a charging abnormality.

"Strange?

How to have a while.

The solar cell film at the bottom of the drone has increased the charging efficiency by more than 50 percent at once....."

Just when Chen Yi was puzzled.

The phone next to it ding-dong.

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

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

Seeing this news, Chen Yi suddenly realized.

"I see...... Thanks to the radar veterans, the energy sent! ”

PS: I chatted with the editor today and asked Sanjiang if there was any hope, and then I got a word, hanging!

Woowoo......
