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, A week later, the American 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's 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 that the reflective layer in the R-7 area has been laid, but the meteorological observatory said there may be a sandstorm 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 by 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 the entire conversation, and could only infer some information from a few words:
"Is there a new satellite threat?"
"Ah, that's right..."
Chang Haonan slammed the car door shut and replied indifferently:
"But it's not a big problem... We won't have to worry about it soon."
At first, Wang Hongrang felt that he didn't quite understand, but then he remembered what Chang Haonan had emphasized just now:
"So that's why you said you want to... confuse reconnaissance satellites?"
Chang Haonan showed a "you're a bit smart" expression:
"In the future, the number of remote sensing satellites will increase. Optical satellites can still be shielded by night, smoke or meteorological conditions, but radar satellites can almost always remain transparent... It's not a good idea to keep hiding like this. We have to find a way to keep 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 Corps is how to counter the enemy's satellite threats.
And with the increasing density and performance of reconnaissance satellites in recent years, the difficulty of this training has increased almost exponentially.
"So..."
"So I plan to lay a circular reflective layer at intervals of 1.5km within 30km around the No. 3 target area, and then with twelve sets of phased array jammers arranged in a triangular shape, the area within a radius of 45-50km can be roughly turned into a radar satellite 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 makes the satellite unable to see the target clearly, which means that 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 use false signals 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 bomb drop area."
At a certain moment, Wang Hongrang thought he had heard it wrong:
"Ah?"
Of course there are many ways to interfere with satellite reconnaissance, and he has used a large part of them himself, but most of them are passive means.
When it comes to active ones, it is basically blinding with directed energy weapons, which is difficult to operate in peacetime.
And like this, being able to directly erase an area from the satellite's view and replace it with a fake reconnaissance result is indeed unheard of.
After a long while, he remembered a somewhat similar concept:
"It's like in the movie... hacking into the backstage of the monitor, replacing the on-site surveillance with a pre-made video, and then infiltrating it?"
Chang Haonan nodded:
"Almost... but I will call it the 'electromagnetic prism' system for the time being."
