Chapter 1372 It’s the Americans’ turn to use anti-aircraft guns to defend against air...


    A few minutes after the "Xuanniao" hit the target, encrypted data from the Mass Effect Range and Maodao radar station were successively transmitted back to the underground command center of Dingxin Base.


    Taking advantage of the decoding skills, Chang Haonan finally waited until the applause ended and made time to answer the questions raised by Jing Zhiyuan:


    "The optical characteristics generated during the warhead fall are our specially designed baits. They will not only not increase the detectability when facing infrared devices, but also have a certain amount of infrared stealth... or strictly speaking, it should be an infrared deception effect. .”


    The audience sitting below were actually immersed in the magnificent scene just now, and they did not concentrate their attention behind the podium when they heard Chang Haonan''s voice.


    Then I heard such a completely unfamiliar answer.


    Jing Zhiyuan, who asked the question just now, even thought he had heard it wrong, but there were many big shots on the scene, so he was embarrassed to ask Chang Haonan to repeat it again, so as not to seem too shocked.


    So, he had to hesitate and glance at the colleagues next to him who seemed as stable as Mount Tai.


    As a result, they could sense the same as their own shock from their eyes and micro-expressions.


    Fortunately, Chang Haonan did not wait for the leader to speak, but gave a more specific explanation after a brief pause:


    "Through the ''thermal barrier trace'' effect, 80% of the thermal energy is derived through the microchannel phase change material in the skin. On the one hand, it can enhance the ionization effect near the surface of the flight body, and on the other hand, it can also enable the observation of infrared channels. The center drifts, and the residual radiation spectrum is also tuned, further reducing the possibility of accurate hits by infrared-guided weapons."


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


    He could even see that Jing Zhiyuan clearly showed a look of wanting to speak but stopping.


    This time I was not worried about being disobedient when asked, but because I didn’t understand too many things and I was really not sure where to ask.


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


    It was obviously a joyful scene, but no one applauded or spoke.


    Only the slight drops made when the electronic device works.


    It was not until about a dozen 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 for a long time, quickly issued instructions:


    "Change the infrared observation results on the Mass Effect shooting range to the big screen!"


    With a clicking mouse button sound, the sensor telemetry interface, which had long lost data on the screen, turned into a picture.


    A picture obviously taken from an infrared device.


    Near the cross line in the center of the picture, a pure black phantom almost dragged into a bolt of lightning, and a dazzling glow enveloped most of the screen around it—


    Some observation equipment in China is affected by the Soviet model. The dyeing method is opposite to the common model. The higher the temperature, the darker the color.


    This color that 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 eyes all came over.


    Chang Haonan had already expected this scene and switched the picture to an ordinary optical channel.


    After changing two rounds, the two channels are clearly superimposed together.


    Now, even an outsider who does not 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 gap presented can basically be considered to be slim in terms of observation distance.


    However, the overall position of the purple light in the optical picture is about two positions away from the infrared channel.


    Not on the cross aiming line.


    Obviously, under the current technical level, the optical observation results are the more accurate.


    That is to say.


    The infrared device is locked in a crooked manner.


    "Dear leaders, this is the effect of aiming at the ''Xuan Bird'' with infrared guided weapons..."


    With the intuitive pictures, Chang Haonan continued to explain:


    "First of all, it is impossible for any existing air defense weapon to track the black bird stably. Even if it happens to be able to capture the heat source, the seeker will occur about 5-10 meters due to the deception effect we set. The offset of the target ended up missing."


    "In most cases, the warheads of ultra-high-speed interceptors use kinetic energy collision and killing, so if they are missed, they will not have any impact. Even if some of them use fragmented warheads, the killing area will be forward conical, and very The ring of air defense missiles is still difficult to destroy our warheads…”


    "..." When talking about this, Chang Haonan could already hear a low but neat audacity from the back of the audience.


    The radar cannot catch it, and the infrared will have a fake lock.


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


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


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


    Finally, the Air Force head said it in a half-joking way:


    "From this perspective, it seems that it was the Americans'' turn to pull out the large-caliber anti-aircraft guns to prevent air defense?"


    The originally tight atmosphere became relaxed instantly.


    Even the front-row leaders showed a laughing expression.


    When the Desert Storm Operation ended in the early 1990s, China looked at the various types of Red Flag 2 air defense missiles in its hands and realized that this thing was very useful.


    So while quickly purchasing the Russian S300 series, he had to draw out a batch of large and medium-caliber anti-aircraft guns to charge.


    At least you are not afraid of electromagnetic interference, you can use barrage to perform cover-type air defense.


    No mistakes, one song, one content, one in 6, one book, one bar, one reading!


    It also became an indescribable pain in the hearts of the air defense forces in that era.


    Now that all guidance methods are ineffective against all their hypersonic weapons, the only thing left for the Americans seems to be this last path...


    Another leader next to him also shook his head with a smile and added:


    "This should be considered as anti-missile use of anti-aircraft guns..."


    When it comes to the keyword "anti-air artillery anti-missiles", someone can''t sit still:


    "Otherwise, we will make a hole in the policy, and we told the Americans that when we were working on the 640 project, we left a 420mm anti-missile cannon. If there is any need, we can sort out the technical data and Offer them at a discounted price…”


    The entire underground command center suddenly filled with joyful air.


    As the first anti-missile interception project of the Republic, the scale and design scope of the 640 Project are extremely large.


    The specific interception methods alone include three sets of solutions: missiles, anti-aircraft guns and lasers.


    Although none of them have been truly applied like the 7010 radar, they have accumulated a lot of useful technologies.


    At this time, Chang Haonan on the stage spent a lot of effort to laugh with him. In order to avoid being unable to hold it in the end, he had to seriously return to the technical topic:


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


    Originally, everyone was just joking about old opponents on the other side of the ocean, and no one would take it seriously.


    As a result, when he heard his words, he immediately became serious.


    The laughter came to an abrupt end.


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


    I saw several intermittent sets of scattered data points appearing on the radar display, but they could not be connected into any smooth curve at all.


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


    Chang Haonan introduced:


    "From the results, it can be seen that traditional missile early warning systems can only capture very scattered data, and the ballistic information forced to be calculated based on this is completely unlimited. For example, this time, the deviation between the calculated landing point and the actual hit position is approximately …”


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


    "About 6,000 kilometers, three times the range of our missile... In short, until the ''Xiongnu'' performs the last orbital maneuver, the other party will not even know where we are aiming."


    Although the psychological threshold of the leaders has been adjusted to a very high, the news is still a bit too explosive.


    "That is to say, the actual reaction time left for the defense is even shorter than the 12 minutes mentioned before?"


    It took a long time before someone asked.


    "If it is calculated by confirming the hit position..."


    Chang Haonan turned his head and looked at the data on the screen:


    "That''s only about half a minute."
