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 has not yet dissipated, Chang Haonan squatted down and grabbed a handful of gravel , watching the cold and fine quartz particles slide down from their fingers: "Since we can avoid space-based reconnaissance by calculating the overhead time of the other party's satellite, the other party can also do the opposite. By doing it, by sudden change Orbital or post-event investigation to obtain some useful information... For example, last week, the American suddenly launched a technical test satellite with the Minotao-4 rocket, although the reason given on the surface was HTV-2 The project verified the reliability of the launch vehicle, but it is hard to guarantee that it is not diverting its sight."
Wang Hongrang followed, looking at the endless snow-capped mountains in the distance, rubbing the frozen red ears :
"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 a few coordinate points on it:
"The 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 brief pause, a little bit of a sudden , and suddenly laughed: "Besides, it is entirely possible that both parts are very important... We have not done such things before."
Wang Hongrang also laughed: "That's true..." Not to mention the distance, just using Dongfeng 16 to test the "Xuanniao" hypersonic verification platform, It can barely be regarded as a typical example of "both parts are important".
In fact, the US side's confusion strategy is quite successful.
The key is to choose the Rockets.
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 Cominotao-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 is indeed difficult 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... to prevent satellite reconnaissance?"
He climbed up the hood of the jeep next to him with agility, looking at the two people wearing desert camouflage in the distance. The technicians who were 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 is not prevention, but confusion..."
He just wanted to explain in detail just now I heard the walkie-talkie next to me suddenly ring;
"Reported, the reflective layer in the R-7 area has been laid, but the meteorological bureau said that there may be sandstorms in the afternoon. Will the original plan continue?"
Sandstorms occur in winter, but to a certain extent That's 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 characters according to the arrangement method of three-three. …”
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 together..."
He sighed helplessly, turned around and opened the back seat door, and pulled out a wired communications that looked like a telephone receiver from inside. Device.
Compared with walkie-talkies used for on-site communication within two kilometers, this regiment-level command radio is actually a device of Wang Hongrang. However, due to the special nature of the effect shooting range, there were few opportunities to use it before. Forget it.
It can now 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 orbit?"
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 evening. , so it doesn’t seem to be really for reconnaissance, it’s 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... Don't expose too much information as much as possible."
In terms of the entire shooting range area, their current actions It's 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:
"Is there a new satellite threat?"
"Ah, that's right..." Chang Haonan slammed the car door and replied indifferently: "But there is no big problem... we won't have to worry soon. "
At the beginning, Wang Hongrang felt that he didn't understand much, but then he remembered what Chang Haonan emphasized just now:
No mistakes, one song, one post, one content One in one in one 6 in nine in one book one bar one read!
"That's why you said you want to... confuse the reconnaissance satellites?"
Chang Haonan showed a "I think you are a little spiritual" expression:
"The number of remote sensing satellites in the future will increase in the number of future generations. , Optical satellites can also be obscured by night, smoke or meteorological conditions, but radar satellites can be kept transparent almost at any time... It is not a way to hide like this, we have to find a way to 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 No. 3 target area, and then combine with the twelve groups arranged in the shape of the product. Phase-controlled array jammer can roughly turn a range of 45-50km into a radar satellite's observation blind spot..."
Wang Hongrang took off his hat and gently scratched 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 his actions have been discovered, which will only make the They mobilize more reconnaissance resources to put more pressure on us."
"Why 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's enough for you to deal with the main traces of the drop-off area."
At a moment, 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.
When it comes to active, it is basically blinding by directional 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... is hacked into the background of the monitor, replaced the on-site surveillance with prefabricated videos, and then penetrated it?"
Chang Haonan nodded:
" Almost...but I call it the 'electromagnetic prism' system for the time being."
