Chapter 1361 Electromagnetic Prism


    "Nothing is impossible."


    A few days later, on the other end of the earth, on the Gobi Desert where the morning mist had not yet dissipated, Chang Haonan squatted down and grabbed the gravel, watching the cold and fine quartz particles slide down from their fingers:


    "Since we can avoid space-based reconnaissance by calculating the over-top time of the other party''s satellite, the other party can also do the opposite and obtain some useful information through sudden orbit change or subsequent investigation... For example, the On the week, the Americans suddenly launched a technical test satellite with the Minotao-4 rocket. Although the reason given on the surface is to verify the reliability of the launch vehicle for the HTV-2 project, it is difficult to guarantee that it is not diverting attention."


    Wang Hongrang followed, raised his eyes and looked at the endless snow-capped mountains in the distance, rubbing the ears that were a little red from the cold:


    "So you think that satellite is the real important part?"


    Chang Haonan took out a notebook with a black cover from his arms and quickly recorded several coordinate points on it:


    "That satellite does not actively send too many signals, and can only confirm that it is not a synthetic aperture radar satellite at most, but it can only be guessed what it does..."


    After a moment of pause, he suddenly laughed:


    "Besides, it is entirely possible that both parts are important... We have not done such things before."


    Wang Hongrang also laughed:


    "That''s true..."


    Not to mention the distant future, just using Dongfeng 16 to test the "Xuanniao" hypersonic verification platform can barely be regarded as a typical example of "both parts are very important".


    In fact, the US confusion strategy has been quite successful.


    The key is the Rockets you choose.


    Generally speaking, if it is a very important load, a relatively safe emission method will definitely be chosen.


    If you want to verify the new Rockets, you can at most hit something less important, or just install a counterweight.


    The situation of Kominotao-4 is quite special.


    As a solid rocket improved by mature ballistic missiles, it is correct to say it is a new model, and there is no problem in being a mature model.


    It''s really hard to make a judgment.


    But Chang Haonan''s principles of acting have always been to prevent problems before they happen.


    "So, we are currently preparing...preventing satellite reconnaissance?"


    He quickly climbed onto the hood of the jeep next to him, looking at two technicians wearing desert camouflage in the distance, busy in the target area No. 3.


    The two were debugging some kind of umbrella-shaped antenna device, and the metal skeleton shone with a cold light under the winter sun.


    As the person in charge of the entire effect range, Wang Hongrang naturally dislikes others to mess around in his responsible area.


    But the person in front of us can''t be judged by common sense.


    Just do it.


    Chang Haonan shook his head and corrected it seriously:


    “Strictly speaking, it’s not prevention, it’s confusion…”


    He just wanted to explain in detail when he heard the walkie-talkie next to him suddenly ring;


    "Reported, the reflective layer in the R-7 area has been laid, but the meteorological observatory said there may be sandstorms in the afternoon. Will the original plan continue?"


    It is not common for sandstorms in winter, but to some extent, this is a good thing for them.


    "Continue, but remember to deepen the fixed piles of the carbon fiber mesh by half a meter, and notify the No. 3 vehicle unit to add another nine sets of antennas, and set them into two sets of small and small shapes according to the arrangement of three-three systems..."


    He decisively issued new orders.


    "yes!"


    Chang Haonan put down the walkie-talkie and was about to continue the topic just now, but the encrypted radio station behind the jeep made a sound again.


    "Why are we all coming together..."


    He sighed helplessly, turned around and opened the rear seat door, and pulled out a wired communication device shaped like a telephone receiver from it.


    Compared to the walkie-talkie used for on-site communication within two kilometers, this regiment-level command radio is actually Wang Hongrang''s equipment, but due to the special nature of the effect shooting range, there were few opportunities to use it before.


    Now it can be used to contact Dingxin, hundreds of kilometers away.


    "Academician Chang, radar information observed that a satellite numbered US-193 had just undergone a change of orbit maneuver about 20 minutes ago. The information about the satellite itself is incomplete, but it is speculated that it should be a synthesis belonging to the National Reconnaissance Bureau. Aperture radar satellite…”


    Chang Haonan thought to himself and asked, "Can they judge their observation focus based on the situation of the new track?"


    The other end of the radio was silent for a while, probably calculating the specific data:


    "The track change is not large, and it is expected to be overturned three hours ahead of the old track, but it is still close to the evening, so it is not very much like it is really for reconnaissance, and it is more likely to be an early drill..."


    Most reconnaissance satellites operate on solar synchronous orbits, which allow satellites to traverse most areas of the earth within approximately 24 hours, and therefore they can pass over the same place at the same time every day and perform orbital maneuvers. Usually to adjust the over-top time to ensure sufficient light, it has little significance for a radar reconnaissance satellite.


    "Forget it, I''ll ask the staff to adjust their arrangements today... and try not to expose too much information as much as possible."


    As far as the entire shooting range area is concerned, their current actions are not big, but Americans still have to respect their ability in the field of intelligence collection.


    Wang Hongrang did not hear all the calls, and could only infer some information from some words:


    “There is a new satellite threat?”


    "Ah, that''s right..."


    Chang Haonan slammed the car door and replied indifferently:


    "But there''s no big problem...we won''t have to worry soon."


    At the beginning, Wang Hongrang felt that he didn''t understand much, but immediately remembered what Chang Haonan emphasized just now:


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


    "So you said you want to... confuse the reconnaissance satellites?"


    Chang Haonan showed an expression of "You are a little spiritual":


    "The number of remote sensing satellites will increase in the future. Optical satellites can also be blocked by night, smoke or meteorological conditions, but radar satellites can be kept transparent almost at any time... It is not a solution to hide like this, we have to find a way to find a way. Take the initiative in our hands.”


    Wang Hongrang was deeply touched by this judgment.


    The most important part of the daily training of the Second Artillery Force is how to fight against the enemy''s satellite threat.


    As the density and performance of reconnaissance satellites continue to increase in recent years, the difficulty of this training has increased almost exponentially.


    "so…"


    "So I plan to lay annular reflective layer at intervals of 1.5km within 30 kilometers around the target area of ??No. 3, and then combine it with the twelve sets of phased array jammers arranged in the shape of a font, which can roughly change the range of 45-50km in the range of radius within a radius of 45-50km. It becomes a blind spot for radar satellites to observe…”


    Wang Hong asked to take off his hat and gently scratch the back of his neck:


    "Isn''t that radar interference?"


    "Of course not..."


    Chang Haonan covered his face:


    "Interference is to make the satellite unable to see the target clearly, that is, the other party will know that their actions have been discovered, which will only allow them to mobilize more reconnaissance resources and put more pressure on us."


    "And confusion is to make the other party think that everything is normal in the area... Although it is impossible to deceive for too long, it is enough for you to deal with the main traces of the drop-off area."


    At some point, Wang Hongrang thought he had heard it wrong:


    "ah?"


    Of course there are many means to interfere with satellite reconnaissance. He has used a large part of it himself, but most of it is passive means.


    What involves activeness is basically blinding by directed energy weapons, and it is difficult to operate this way in peacetime.


    And like this, I have never heard of the fact that I can directly erase an area from the satellite''s field of view and replace it with a fake reconnaissance result.


    After a while, he remembered a somewhat similar concept:


    "It''s like the kind of operation that goes into the background of the monitor, replaces on-site surveillance with pre-made videos, and then penetrates in?"


    Chang Haonan nodded:


    "Absolutely...but I call it the ''electromagnetic prism'' system for the time being."
