"It seems that the red side still has a lot of ideas, and takes advantage of the night to break into the ribs of the first line of defense of the blue side......"

"After dawn, the blue side's digital synthesis battalion will face an unfavorable situation of attacking from both sides!"

After only looking at it for a while, Du Zhongping roughly understood the tactical intentions of the red side.

After listening to President Du's analysis, several bigwigs around him nodded in agreement.

Li Zhenxiang frowned and looked at it for a while, and couldn't help but ask: "The idea of the red side is good, but the risk is a bit big, right?" ”

"If it is detected by the blue positional radar, it is easy to become a lonely!"

As soon as Li Zhenxiang's words fell, Tian Songren explained with a smile.

"Deputy Commander Li, you don't know anything. We, the C Military Region, have recently developed a completely new radio jamming technology. ”

"Once in use, it can shield all radio monitoring ...... within a radius of 10 kilometers in a short period of time."

Tian Song Renzhi said proudly: "Although the blue side, the digital synthesis battalion, has both communication troops and electronic countermeasures troops, the numerical disadvantage is still too obvious. ”

"Without understanding the information jamming technology of the red side, it is difficult for them to respond in a timely manner."

Regarding Tian Songren's self-confidence, Li Zhenxiang did not refute anything.

But deep down, he also has absolute confidence in Su Qiyue's level of information technology.

Li Zhenxiang firmly believes that even without warning in advance, Su Qiyue can quickly come up with a solution after the red side has used information jamming methods.

There was silence in the conference room for a while, and when he saw that the red side's information jamming methods had been activated, Du Zhongping spoke up.

He looked back at Qin Zhongpei and asked, "Minister Qin, can you still connect to the picture at the headquarters of the Digital Synthesis Battalion now?" ”

"Yes, Chief Du."

Qin Zhongpei said concisely.

In fact, long before the exercise began, several bigwigs of the director team on the side of the headquarters operations department had specifically mentioned the digital synthesis battalion.

Because he knew Su Qiyue's ability and changeable tactics, Qin Zhongpei and several other bigwigs made a decision unanimous.

The director team has set up a special observation group in Su Qiyue, a battalion-level combat unit, which can ensure the uninterrupted transmission of pictures and audio 24 hours a day.

In previous exercises, such specialized observation groups were usually only visible to the divisional headquarters of combat units.

After listening to Minister Qin's answer, Du Zhongping was full of relief and said, "That couldn't be better." ”

"Minister Qin, pass over the picture of Su Qiyue's camp. I want to see if their digital synthesis battalion can react immediately in the face of this unknown threat. ”

"After reacting, can you respond in time?"

After Chief Du spoke, Qin Zhongpei quickly gave an order to the staff in charge of information transmission in the director's department.

At this time, although the staff has changed a group on duty.

But during the day, everyone also listened to the reminders of their comrades-in-arms in the same position.

For Su Qiyue and their digital synthesis camp's movements, everyone has never relaxed their attention.

Therefore, as soon as Minister Qin's order was issued, the picture of the headquarters of the Blue Side's digital synthesis battalion had already appeared on the big screen.

……

"Report to the battalion commander that there is an abnormality in the transmission of information from our communications platoon and electronic countermeasures platoon, and there is a disorder in several channels."

At the headquarters of the synthetic battalion, Ma Xiaoshuai, who came in in a hurry, was reporting to Su Qiyue.

"Has the frequency range to be interfered with determined?"

Su Qiyue asked calmly.

"It's not decided yet."

Ma Xiaoshuai explained, "At present, it is known that both short-wave and ultra-short-wave frequencies have been interfered with. ”

"For the time being, our positional radar has lost its reconnaissance capability within a range of 10 kilometers."

Su Qiyue answered, and there was not much surprise on his face.

The modes of military combat communication are roughly divided into radio communications, wired telecommunications, optical communications, motion communications, and simple signal communications.

Among them, radio communications are the most widely used because they are established quickly and are less affected by geographical conditions, and they are also the main means of communication to ensure modern combat command.

One of its greatest advantages is that it can establish communication with troops and detachments whose location is unknown, divided by the enemy, or blocked by natural obstacles.

Of course, the drawbacks of radio communication also exist objectively.

Its signal can be easily intercepted, direction-finding and jamming by the enemy.

In its use, it is necessary to take measures from the organizational and technical aspects.

The synthetic brigade of the red side, as a modern synthetic unit, the electronic countermeasures battalion is definitely its standard.

It is not unusual for such radio interference to exist.

Being able to block their own channels of several wavelengths at the same time, their level of electronic countermeasures battalion is quite passable.

However, why did Red use this electronic countermeasure at this point in time?

Is it just because of the high visibility during the day, and it doesn't work?

After touching his cheeks and muttering for a while, Su Qiyue probably had a judgment.

"Give an order to the communication platoon and switch to frequency hopping communication!"

Su Qiyue quickly gave instructions.

Ma Xiaoshuai was slightly stunned, and asked hesitantly: "Battalion commander, frequency hopping technology, I just saw it from the electronic science and technology newspaper some time ago." ”

"Over there in the communication platoon, I'm afraid I haven't mastered this technology for the time being......"

Su Qiyue was stunned for a moment, and then reacted.

Indeed, in this day and age, radio frequency hopping communication technology is not widely used.

Especially when this kind of electronic countermeasures are in the military, most of the technicians have not yet mastered this technology.

After a moment of silence, Su Qiyue opened his voice and said: "In this way, you and I will go to the communication platoon to have a look, and I will explain the operation principle to everyone, and then demonstrate it." ”

"That's great! Battalion commander, you personally taught the skills, everyone must be very happy! ”

Ma Xiaoshuai said happily.

Indeed, the technical level of information security in the entire B Military Region has been deeply rooted in the hearts of the people.

The technicians of his own digital synthesis camp regard the information technology course he created as a guideline.

Being able to get the personal guidance of the battalion commander will definitely not miss this opportunity.

Following Ma Xiaoshuai to the communication platoon, Su Qiyue sat down in front of the first computer and began to operate and demonstrate at the same time.

"The so-called frequency hopping precisely means: multi-frequency frequency shift keying with a certain code sequence for selection."

"In other words, the frequency shift keying modulation is carried out with a spread spectrum sequence, so that the carrier frequency is constantly changing."

"The working principle is as follows: in the transmitter, the input code modulates the carrier wave with frequency f0 to obtain a modulated signal with a bandwidth of Bm."

"The independently generated frequency-hopping accumulator controls the frequency synthesizer to output the local oscillator signal of the frequency hopping in different time slots. It is used to convert the frequency of the modulated signal, so that the frequency of the RF signal after frequency conversion is pseudo-randomly jumped, that is, the frequency hopping signal. ”

"In a receiver, the local frequency hopping sequence controls the synthesizer so that the frequency of the output local oscillator signal jumps accordingly with the sender frequency."

"The local oscillator signal of the jump transformer is converted to the received frequency hopping signal, and the frequency is moved back to realize the dejump. After dejumping, the modulated signal is demodulated under the action of the local carrier, and the signal output code is restored......"

Speaking of which, Su Qiyue's fingers have completed a series of operations.

Soon, the signal transmission and reception of the computer in his hand had been restored.

……

In the conference hall of the director's department, seeing that Su Qiyue was able to deal with the communication interference of his own red party so quickly, the muscles on Tian Songren's face trembled.

The other bigwigs of the C Military Region, such as Deputy Chief of Staff Xiang Qiangjun, Commander of the R Group Army Chen Haoruo, Political Commissar Duan Zifeng, and others, also changed their faces.

These people have long been aware of this information jamming technology of the electronic countermeasures battalion of the digital synthetic brigade.

Speaking of which, this technology is not the first of its kind in the synthetic brigade, it was invented by Jiang Yuerong, an engineer of Division C.

With her technological invention, the level of information confrontation of Division C completely crushed Division A, the main division at that time.

Because of this, Jiang Yuerong became attached to the chief of staff of Division C at that time.

Later, after the two got married, the Jiang Gong resigned from the position of a special engineer of Division C.

And this technology was also disclosed from the side of Division C.

On the side of the synthetic brigade, Tang Long, deputy chief of the combat section, is also from a technical background.

He naturally admired Jianggong's invention very much.

After he carried it forward, now the technology has been perfected and promoted to the entire R Army.

Judging from the eyes of Chen Haoruo and Duan Zifeng, Jiang Yuerong and Tang Long have successively made great efforts to develop this "multi-frequency information jamming system", which should be a very advanced technology.

But the young man named Su Qiyue on the screen actually cracked it casually.

Moreover, it was so neatly broken.

Such a result is really difficult for several of them to accept.

Mr. Du didn't seem to be surprised by Su Qiyue's performance.

He looked at Liu Zhibin, a member of the director's department, the chief engineer of information technology at the headquarters, and asked: "Chief Engineer Liu, does this 'frequency hopping' method that this kid just used in July make sense?" ”

Liu Zhibin, who has gray hair, is over sixty years old, but he is full of energy.

At this time, he was watching with relish as Professor Su Qiyue used frequency hopping technology by the communication platoon personnel.

After listening to President Du's inquiry, he reluctantly turned his gaze back.

"Mr. Du, Researcher Su's technical means are really eye-opening. His thinking and ideas are so advanced! ”

Liu Zhibin sighed with emotion: "There is nothing new in frequency hopping technology, and it has been used abroad for a long time. ”

"The key to the maturity of this technology lies in the anti-interference ability of the frequency hopping communication system. Among them, the strength of this signal and the ratio of the bandwidth of the demodulated signal are important indicators to measure this. ”

"Now looking at the technical means used by researcher Su, the signal-to-noise ratio at the communication outlet has been well improved after the RF signal has been deexpanded by the machine in the noisy environment."

"Even by international standards, he has reached the ......"
