Chapter 1372 Now it's the Americans' turn to use anti-aircraft guns...

A few minutes after the "Xuanniao" hit the target, encrypted data from the mass effect target range and the Maodao radar station were transmitted back to the underground command center of the Dingxin base.

While decoding, Chang Haonan finally waited for the applause to end and took the time to answer the question raised by Jing Zhiyuan:

"The optical signature produced by the warhead during its descent is a specially designed decoy. It not only does not increase the detectability of infrared equipment, but also has a certain infrared stealth effect... or strictly speaking, it should be an infrared deception effect."

The audience sitting below were actually still immersed in the magnificent scene just now, until they heard Chang Haonan's voice and then they focused their attention back to the podium.

Then I heard an answer that was completely counterintuitive.

Jing Zhiyuan, who asked the question just now, even thought that he had heard it wrong. However, there were so many bigwigs at the scene that he was embarrassed to ask Chang Haonan to repeat it again, so as not to appear too surprised.

Therefore, he could only glance hesitantly at a few colleagues next to him who seemed as steady as a rock.

As expected, I could tell from their eyes and micro-expressions that they were as shocked as I was.

Fortunately, Chang Haonan did not wait for the leader to speak, but paused for a moment before giving a more specific explanation:

"Through the 'thermal barrier tracer' effect, 80% of the heat energy is conducted through the microchannel phase change material in the skin. On the one hand, it can enhance the ionization effect near the surface of the flying body. On the other hand, it can also cause the observation center of the infrared channel to drift. The remaining radiation energy spectrum is also tuned, further reducing the possibility of being accurately hit by infrared guided weapons."

This section is indeed a bit abstract, especially for laymen.

He could even see that Jing Zhiyuan had an expression that showed hesitancy in speaking.

This time I wasn't worried about asking questions that were inappropriate, but because there were so many things I didn't understand and I wasn't sure where to start.

For a moment, the atmosphere in the entire venue became a little strange.

It was clearly a joyous scene, but no one applauded or spoke.

There was only the slight beeping sound of the electronic equipment working.

It wasn't until about ten seconds later that a technician behind the console finally broke the silence:

"Report, data decoding has been completed!"

Chang Haonan, who had been waiting for this sentence, quickly issued instructions:

"Turn the infrared observation results of the mass effect range onto the big screen!"

With a series of clicking sounds of mouse buttons, the sensor telemetry interface that had long been free of data on the screen turned into a picture.

A picture that was obviously taken with infrared equipment.

Near the crosshairs in the center of the screen, a pure black shadow almost resembled a streak of lightning, and a dazzling glow enveloped more than half of the surrounding screen.

Some of China's observation equipment are influenced by Soviet models, and the coloring method is opposite to that of common models, that is, the higher the temperature, the darker the color.

This color, which is close to pure black, is undoubtedly an extremely obvious feature.

It seems to be inconsistent with what Chang Haonan said.

More than a dozen puzzled glances were cast over at the same time.

Chang Haonan had already anticipated this kind of scene and switched the image to the ordinary optical channel.

After changing back and forth twice, the images of the two channels were superimposed together with clear meaning.

Now, even an outsider who doesn't understand technology at all can see the key point -

Although the positions of the two channels on the same device are not exactly the same, the angle difference presented is basically negligible in terms of observation distance.

However, the overall position of the purple light in the optical image is about two body lengths away from the infrared channel.

Not in the crosshairs.

Obviously, at the current level of technology, the optical observation results are more accurate.

In other words.

The infrared device lock is crooked.

"Commendations, this is the effect produced when infrared guided weapons are aimed at the 'Xuan Niao'..."

With the help of intuitive pictures, Chang Haonan continued to explain:

"First of all, it should be noted that it is impossible for any existing air defense weapon to stably track the Xuanniao. Even if it happens to capture the heat source, the seeker will deviate by about 5-10 meters due to the deception effect we set up, and eventually miss the target."

"In most cases, the warheads of hypervelocity interceptors use kinetic collision to kill, so if they miss, they will not have any impact. Even if some of them use fragmentation warheads, the killing area will be a forward cone, rather than the ring shape of conventional air defense missiles, so it is still difficult to destroy our warheads..."

"..."

When he said this, Chang Haonan could already hear low but uniform exclamations coming from the back row of the audience.

Radar cannot capture and infrared will falsely lock.

The two most common guidance methods have all become ineffective, and pure optical guidance is almost impossible to use in the field of medium and long-range air defense.

At this moment, the same thought appeared in the minds of many air force officers.

But the leader was present, so no one could speak rashly.

Finally, the head of the Air Force said it half-jokingly:

"Looking at it this way, it seems like it's the Americans' turn to bring out their large-caliber anti-aircraft guns for air defense?"

The originally tense atmosphere suddenly became relaxed.

Even the leaders in the front row couldn't help laughing.

When Operation Desert Storm just ended in the early 90s, China looked at the various types of Hongqi-2 air defense missiles in its hands and realized that they were of little use.

Therefore, while quickly purchasing the Russian-made S300 series, they had to pull out a batch of large and medium caliber anti-aircraft guns to make up the number.

At least it is not afraid of electromagnetic interference and can launch barrages for covering air defense.

It also became an unspeakable pain in the hearts of the Air Force Air Defense Force of that era.

Now, all guidance methods have failed to meet the hypersonic weapons of the United States, so it seems that the Americans only have this last way left...

Another leader beside him also smiled and shook his head, adding:

"This should be considered as anti-missile defense with anti-aircraft guns..."

When the keyword "anti-aircraft guns and anti-missiles" was mentioned, some people could not sit still:

"Or we can make a policy change and tell the Americans that we left behind a 640mm anti-missile cannon when we were working on Project 420. If there is a demand, we can compile the technical data and provide it to them at a preferential price..."

The entire underground command center was suddenly filled with a happy atmosphere.

As the Republic's first anti-missile interception project, Project 640 was extremely large in scale and design scope.

There are three specific interception options: missiles, anti-aircraft guns and lasers.

Although none of them were actually put into use like the 7010 radar, they still accumulated a lot of useful technologies.

At this time, Chang Haonan on the stage had to use a lot of effort not to laugh along. In order to avoid being unable to hold back, he had to seriously switch back to the technical topic:

"In fact, even if they really bring out anti-aircraft guns, it is completely impossible to intercept them by covering fire."

Originally, everyone was just joking about their old rivals on the other side of the ocean, and no one took it seriously.

As a result, when they heard his words, they all became serious.

The laughter also stopped abruptly.

Chang Haonan signaled the operator to switch the screen to the data transmitted from the Maodao radar station.

All I saw on the radar screen were a few discontinuous groups of scattered data points, which could not be connected into any smooth curve.

"Although the strategic early warning radar we tested this time is smaller in scale, its working principle and early warning process are almost the same as those of similar products in the United States and Russia."

Chang Haonan introduced:

"From the results, we can see that the traditional missile early warning system can only capture very scattered data, and the ballistic information forcibly inferred from it is completely irrelevant. For example, this time, the calculated landing point deviated from the actual impact position by about..."

He quickly calculated the distance between the western part of Longyuan Province and the eastern Mediterranean:

"About 6000 kilometers, three times the range of our missiles... In short, before the 'Xuanniao' performs the final orbit change maneuver, the enemy won't even know where we are aiming at."

Although the psychological thresholds of the leaders had been raised very high, this news was still a bit too explosive.

"In other words, the actual reaction time left for the defenders is even shorter than the 12 minutes mentioned before?"

After a long time, someone asked.

"If we calculate based on the confirmed hit location..."

Chang Haonan turned around and glanced at the data on the screen:

"That was only about half a minute or so."
