Open an aircraft carrier to fight against Japan

Lin Yuan then turned off the video call equipment, and Yu Feng also began to prepare for the next day's battle.

The next day, at [-] o'clock in the morning on February [-]th, Togo Heihachiro led the fleet to arrive at the predetermined sea area, and then ordered the destroyer squadron to spread out into a search formation, looking for the fleet of Lin Yuan's troops in the Chongjin sea area. At this time, the Japanese army was a The column changed its formation immediately after hearing the order, and the destroyer squadron at the front spread out into a horizontal formation, and each warship was separated by five kilometers, searching forward.

The sixteen destroyers of the Japanese army can fully search the sea area of ​​more than 80 kilometers. At 06:30 in the morning, the Japanese destroyer squadron completed its formation change. At [-]:[-] in the morning, the sky began to brighten. Order: "Increase the speed to [-] knots, and search for the warships of Lin Yuan's troops."

The destroyer team was searching ahead, and the four battleships and four battlecruisers were hiding ten kilometers behind. According to the Japanese army's combat plan, the destroyer first launched an attack in this operation. After the destroyer found the target, it released a large number of torpedoes. These torpedoes The warship that can sink Lin Yuan is the best. If it cannot be sunk, it will disrupt Lin Yuan's fleet.

Commander of the Japanese Combined Fleet Togo Heihachiro, Chief of Staff Akiyama Shinyuki, and Anderson, the representative of the United States Arms Company, were standing in the command room of the flagship Ise ship. Togo Heihachiro asked Anderson: "Mr. Anderson, how is the working condition of our radar alarm Like? Are you okay?"

Anderson smiled and said: "No problem, everything is normal, as long as the electromagnetic waves emitted by the radar of Lin Yuan's troops hit us, we will be able to know in advance."

Dongxiang Heihachiro nodded, and then asked: "If we find the electromagnetic waves emitted by the radar of Lin Yuan's troops, can we know the position of Lin Yuan's troops based on this electromagnetic waves?"

Anderson smiled helplessly, and said: "General Dongxiang's technical attainments are really extraordinary. This is the truth, not flattery. Our domestic experts are conducting research on this topic, and we have not yet developed a feasible technology. Find the location of the emission source in the electromagnetic waves."

Dongxiang Heihachiro nodded lightly, and said: "The current Lin Yuan troops must be looking for us, I wonder if they will find us?"

Anderson didn't answer. At this moment, the in-ship communicator in front of him suddenly rang. Togo Heihachiro saw that it was from the communication room, so he picked up the receiver and asked, "Communication Officer, what happened?"

The chief of communications replied: "Report to the general, our communication has been interfered by Lin Yuan's troops."

Of course Dongxiang Heihachiro knew that Lin Yuan's troops had the ability to interfere electronically. Under the interference of Lin Yuan's troops, the chariot unit could only fight on its own, and the result was a complete defeat!Dongxiang Heihachiro felt a chill on his back, and said, "Is the interference serious now?"

The communications chief said: "Our communication with the destroyer team has been affected to a certain extent. Your Excellency, should we use frequency hopping to avoid the electromagnetic interference from Lin Yuan's troops?"

Dongxiang Heihachiro said: "No, Lin Yuan's troops have blocking jammers. If we hop frequency now, they will definitely start blocking jamming. Don't frequency hop yet."

"Yes, I see," said the communications chief.

Dongxiang Heihachiro just put the microphone back in place, only to hear Akiyama Shinyuki shout loudly: "Lin Yuan's troops interfered with us? Impossible, this is impossible!"

Dongxiang Heihachiro hurriedly asked: "Why is it impossible?"

Akiyama Shinyuki said: "Although I don't know much about electronic technology, I also know that if the jammer wants to accurately interfere with the target, it must point the antenna at the target that needs to be interfered, so that the energy of the electromagnetic interference can be concentrated in one direction to achieve The purpose of interference, if Lin Yuan's troops can interfere with us, it means they have spotted us! But the radar alarm did not go off, which means that we were not discovered by Lin Yuan's troops at all, so how did they interfere with us?"

Heihachiro Togo looked at Anderson and said, "Mr. Anderson, is there something wrong with your radar alarm?"

Anderson said: "Impossible, we just checked, it is very sensitive to electromagnetic signals."

Dongxiang Heihachiro said: "But Mr. Anderson, the electromagnetic interference of Lin Yuan's troops is also electromagnetic waves. Why didn't your radar alarm detect them?"

Anderson said: "Lin Yuan's troops use targeted jamming. The frequency of the jamming wave is close to our communication frequency. In order not to be interfered by the communication frequency on your warship, our radar alarm has a filter circuit. This circuit can Filter out the electromagnetic waves on the communication frequency of our warship, and will not call the police."

Dongxiang Heihachiro said: "But how do you explain the current situation? Could it be that what Akiyama Shinyuki said is wrong?"

Anderson said: "Chief of Staff Akiyama is right. Electromagnetic interference does require the antenna to be aimed at the target to be interfered with, but..." Anderson suddenly changed his voice when he said this, and said, "I'll go to our operating room to have a look. .”

After Anderson finished speaking, he came to the operation room of the radar alarm in two steps in three steps, and said as soon as he entered the door: "Have you received an unfamiliar electromagnetic signal?"

The operator replied: "It's all background noise, no enemy's electromagnetic signal has been detected."

Anderson said: "Check the alarm. Is there something wrong with it? The warship of Lin Yuan's army has spotted us. Why didn't we notice it?"

The operator said in surprise: "There is such a thing? I will start the self-detection circuit!" As he spoke, he pressed a few switches on the operation panel, and a green light came on in a short while, and the operator said: " The detection circuit shows that there is no problem with the radar siren."

Anderson said: "No problem? Then why can't we perceive electromagnetic waves? Turn off the filter circuit and see if there is any response to our own communication waves."

The operator then turned off the filter circuit, and the buzzer immediately sounded an alarm. Anderson said: "This is strange, our alarm is fine, why didn't we find the electromagnetic waves of Lin Yuan's troops?"

Anderson's radar alarm is not broken, but they underestimated the strength of Lin Yuan's troops. The radar of Lin Yuan's troops is the airborne radar of J-25. This radar uses special technology to make this radar have low detectability. To put it simply, the radar of Lin Yuan's troops can detect the enemy, but the enemy's radar alarm cannot detect Lin Yuan's radar.

This kind of performance depends on the high sensitivity of the receiver, and the technical background in it is very deep. Although Anderson and the others have invested a lot of money and energy in the field of radar technology, how can their technical ability be compared with that of Lin Yuan? than what?

At this time, a messenger came over and said to Anderson: "Mr. Anderson, Commander Dongxiang, please go back to the command room, and now we are going to deploy anti-missile operations!"

Anderson returned to the command room and said to Togo Heihachiro, "I'm sorry, our radar warning device didn't work."

Togo Heihachiro shook his head and said, "It doesn't matter, as long as your interference wires can work, we can still win in one fell swoop."
