sometimes

In the confrontation between powerful countries with first-class military strength, the most important place for military strategists is the cutting-edge scientific and technological means. To be more specific, the key factor that determines the outcome is information technology.Attacks beyond visual range or even across continents all rely on electronic reconnaissance. In the battle, whichever side's command center has more complete information, interception, analysis, identification and positioning capabilities are stronger, which side is invincible.

But once a war starts, you have reconnaissance means, and I also have anti-reconnaissance measures. There are often hundreds of radar base stations sending and receiving signals in the war zone and even the surrounding detection range, thousands of communication channels working at the same time, and countless false signal stations. , to help darken space satellites in icy outer space orbits.

Facing such a complex electromagnetic environment, the signal captured by the receiver is chaotic, and the probability of false alarm is relatively high.Information is the life of fighter planes and pilots. If it cannot be quickly identified, countless false targets will appear on the instrument, which will interfere with judgment and affect decision-making.The electronic warfare support system sensors equipped on submarines are of great significance in actual combat, which is equivalent to adding a pair of "eyes" in the battle situation, which can help the command center to further screen signal sources, which is even more powerful for the fighter jets of the Skytracer.

This technology is based on the accumulation of achievements of several generations, and it is extremely professional. The thick book of principles and signal processing materials sent to Jun Yang is only a superficial summary. After the training, they have to keep the materials intact. return.Four to five hundred pages of content, two or three days is not enough to scan and archive, and it is impossible for the human brain to memorize them all.

The teacher can't wait to bring out ten pages of content in one sentence. At first glance, it is all human words, which is not difficult to understand.Subconsciously, Jun Yang wants to remember more in case of emergencies, but the time constraints are strict, and he feels restless when he thinks about it.

The students around seemed quite congenial, chatting for a while.At this time, after listening carefully, he discovered that these classmates who disappointed him and didn't intend to pay attention to them all had a lot of background: some were researchers from a certain science and technology college, some were representatives of the electronic countermeasures force, and some were inheriting their father's career—not only The content in the book can be easily talked about with just a glance, and the editor is also related.

How come everyone's predecessors have made great achievements, and every family has a long history of learning?

Jun Yang put the pen in his mouth.

He didn't have such predecessors to think about, so he thought about Yan Mingxin for a while.

In detail, from unfamiliarity to familiarity, he has never heard Yan Mingxin take the initiative to talk about the glorious deeds of Captain Yan. Even when he mentions his father occasionally, he often complains in a low voice.It seems that to Yan Mingxin, Captain Yan is neither the captain nor the chief, but just a father.

Yan Mingxin has never shown "hate the poor and love the rich" towards him. What was the relationship between the two when they were in the Shanhaiguan Military Region, and it was still the same when they came to Fengtian...Of course, it has gotten better recently.

Jun Yang smacked the plastic pen holder, giving out a bit of "humanity"—whether he has the ability to enter the heavens or the earth, or grows into a radiant appearance, Yan Mingxin is always there every morning, night, hour, He never forgot that he is an ordinary and lovely person.He lives freely, not in the praise of others, nor in order to squeeze into other people's windows, he follows his own heart, even if it is hardship or suffering.

The more he is so real that people can touch it, the more unrealistic the illusion will be. He is obviously not a magician with ingenious calculations, nor is he a rich man with a lot of money, but when you get close to him, the suffering in the world is not worthy of being mentioned. Embrace him, the road of pursuing fame and fame can also have mountains and rivers, at least it is not worth forgetting yourself.

Jun Yang could feel that Yan Mingxin was always on guard against him, preventing him, a widow and orphan, from relapsing his old illness, so he held a can of chicken soup in one hand, ready to give him a sip at any time.Of course he was unwilling, but sometimes he was careless and couldn't help it, and he was poured in with one mouthful.He never thought that the sour ideal that he hadn't mentioned for a long time would become sweet again, and the land that had been dry for many years could also have some vitality. When he looked up again, he saw clearly that Yan Mingxin himself was the person who walked all the way from childhood. Come and lose the pure white all the way.

Jun Yang reopened the file calmly.

Of course, he still couldn't remember it.

When he turned the page, he thought of his series of actions, and found it very funny.

It was like seeing Yan Mingxin himself from a distance, and he couldn't help but want to laugh.

In the last afternoon, in order to check the learning results, the teacher called up several cases for everyone to answer and analyze. Four dynamic radar images appeared on the screen at the same time.

The Proud Sons of Heaven focused their attention on identifying them, but without any specific circumstances as a reminder, these pictures were so broad that people couldn't figure it out: "The first one is a segmented scan, one lead plane and two wingmen..."

"Well, this one is for anti-ship warfare..."

"...Also, this one is dropping an anti-ship bomb on an enemy ship."

Jun Yang stared at it for a long time, then suddenly said: "The prelude to the Mobi Salo air strike."

The teacher took the small rod a little and signaled him to get up: "How do you know?"

"Report." Jun Yang got up and replied, "These four pictures reflect the same battle situation. In the first picture, the radar picture has obvious fanning area and strong directivity, and it is only launched when it scans friendly aircraft around The data link is used for directional guidance. This is obviously the radar picture on an early warning aircraft. Second, after it successfully approaches the target, it is ready to launch an attack. , the chaff slowly fell in the air, resulting in countless "unknown targets" appearing in the picture on the lower left, and triggering an air raid alarm. If the first two judgments are correct, the picture on the upper right is the radar of the tactical bomber sharing the data link The picture, because it shares resources with the early warning aircraft and electronic jammer, so the chaff in the air will not interfere with it, and its radar display always only shows the warship. The last picture is the radar picture detected by the friendly underwater submarine of the warship. A target suddenly split into four or five hostile targets, and then disappeared, indicating that the ship had been shot at this time, and a large piece of the ship's side was blown away. Threat, so no longer displayed."

The meeting room was silent.

The instructor nodded: "Your analysis is completely correct, but how did you know that this was the prelude to the Mobi Salo air strike?"

"First, the above equipment has certain age characteristics. Second, in the radar screen of the submarine, there is a square building on the sea in the southeast direction." Jun Yang said lightly, "According to the "History of World Wars", more than 200 years ago, this ship The cruiser in area Y was patrolling near the offshore drilling platform, and found that the enemy planes in area A were suspected of invading, so they went out to meet the enemy. Since the first wave of air attack electronic interference in area A did not achieve full frequency domain coverage, part of it was successfully intercepted by the cruiser air defense network, so The keel was not destroyed, and the ship's damage control was done properly. Although the cruiser was shot and lost its combat effectiveness, it did not sink. It succeeded in grabbing a beach on an island 6 nautical miles to the west. Judging from the chart, it is now marching The heading is to the west. Area A did not launch a second air strike in a short period of time because their commander decided to concentrate their firepower on Mobisallo. Based on the above, I judge that this is an electronic replay of the prelude to the Mobisalo air strike."

"That's right, please sit down." The teacher said, "I'll play this episode again, and others will deduce it according to his analysis."

The second replay was more complicated, and the instructor still played it in video format. This time it was a radio wave intercepted by a passive surveillance device.Among them, the electronic interference sound covered almost the whole process, and the chance to hear the human voice was only a few seconds.It was an old man's voice, with a deep resonance, and he couldn't hear what he was saying at all.

While everyone was holding their breath, Jun Yang said, "Beheading."

Any action to eliminate hostile leaders can be called "beheading", and there are too many examples in history.

The instructor asked: "What year is it?"

Jun Yang lowered his eyes and listened for a moment: "In 2213, the number one person in T area."

The teacher nodded to him: "Say it."

"There was a civil war in Area T at that time. The militants used drones to intercept a phone call from Person No. [-], and quickly launched a source-finding attack, blowing up the shelter of Person No. [-]." Jun Yang said calmly, "About this part of the review , I'm sorry, because I'm more sensitive to sound, I heard a little of what he said on the phone."

In the third replay, Jun Yang just watched it for a few seconds, and immediately blurted out: "Baima Pass air strike, Jiaolong Bay."

The instructor couldn't help but let out a "huh" and pressed the pause button: "You are too fast. How do you know? Wait, I haven't asked you yet, which unit are you from?"

"Fengtian Naval Aviation Flying Academy, Junyang." He said, "Before that, I was a fighter pilot in the Shanhaiguan Military Region, and I was there on the day of the Baimaguan air raid."

"No wonder." The instructor thought about it, "Then, you sit down first and let the other students watch for a while."

Jun Yang said calmly, "Yes."

Even though they knew it was a replay of the air raid at Baimaguan, the students talked about it in a hurry, but they couldn't restore the whole picture completely and correctly.

The instructor ordered Jun Yang again: "You can add."

"Area D used 'non-technical means' to obtain our signal frequency in advance before the air strike. The jammer was saturated and suppressed before, and released electronic jamming against this frequency. The rest of the fighters remained silent and marched in depth. Because there is no The early-warning aircraft detected, and the enemy fleet flew over Jiaolong Bay and encountered us unexpectedly, and an exchange of fire occurred." Jun Yang was very familiar with this passage, and he spoke very fluently, and even mentioned the plot that was not reflected in the screen, "Part [-] One is the picture of our early warning aircraft. After the electronic jammer is shot down, the signal is unstable, and the data link appears and disappears. The second picture is the integrated screen display of the air fighter. The pilot quickly switched channels after being electronically suppressed, so the top of the screen The number of the communication channel of the company jumps. The third picture is restored from the flight recorder of the captured enemy plane. In this picture, the ground oil depot and launch pad at Baimaguan are their preset targets. The fourth picture is The picture of our underwater submarine in Jiaolong Bay, because the enemy's electronic jammer was shot down, we successfully carried out electronic counter-suppression, and the submarine radar captured the escape direction of the remaining enemy planes. According to the "International Law of Naval Warfare", we have the right to carry out hot pursuit Right, before chasing to the contiguous area, shot down another one."

After the training was over, Jun Yang went back to the temporary dormitory to pick up his luggage.

The teacher appeared out of nowhere and walked with him: "Why are you leaving in such a hurry? Others are still chatting there. I think you rarely communicate with people? If you have any questions, you can tell me."

"No." Jun Yang kept walking, "I just don't like talking."

"Oh, that's good." The teacher said, "It's not a bad thing to get used to being alone. Sometimes, there are many people who were born in the same era and witnessed the same thing, but not everyone who has experienced it can be like you. Good at summarizing. Even if you have personally experienced the air strike at Baimaguan, other combatants may not have your reaction speed. I am looking forward to working with you."

When Jun Yang heard this, his face changed—in the past, he could at least look at the sea through the porthole, breathe fresh air freely, and go to the sky to perform duties from time to time. If he was in the submarine force, he would have to lurk underwater for two months in a mission cycle. The sky is dark and life is hard.

He didn't know who this person was, and he was afraid that if he spoke with weight, he wouldn't be able to leave.

Just in case, and completely dispelled the other party's thoughts, he stopped and replied solemnly: "Don't expect - we guard the same land, isn't this already working together?"

Not sure how the other guy who worked with him was doing this weekend.

Jun Yang returned to the college non-stop, opened the door of the dormitory, and saw a note on the ground at a glance.

"Yan Mingxin is here for a visit."

There are a lot of missed calls in his mobile phone, and there are a few numbers that he has not contacted before, which should be called by Yan Mingxin.He knew that even if he called back now, he would definitely not be able to find anyone, so he could only wait for Yan Mingxin to call again.

It's a pity that his mobile phone hasn't rang for a long time, because the five-in-one sea, land, air, space, and electricity joint training on the anniversary of the naval battle has kicked off with Jiaolong Bay as the center.

The ammunition of Fengtian Air Force Base was out of the warehouse, and the fighter planes were out of the warehouse. A large group of twelve pilots and hundreds of maintenance personnel were all ready for battle. They only waited for an order to be dispatched immediately.

The author has something to say: Thanks to everyone’s cute support, it’s finally going to be difficult to get into V after washing warm oil. Tomorrow I want to fix the little bully in the previous chapters. It’s mainly about the data (should be) stopped for a day,~ Well, I will enter V (probably) the day after tomorrow, please support qwq more!
