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 four o'clock in the morning on 18 February, Togo Heihachiro led the fleet to arrive at the predetermined sea area, and immediately ordered the destroyer detachment to disperse into a search formation to search for the fleet of Hayashi's troops in the Qingjin sea area.

At six o'clock in the morning, the Japanese destroyer detachment completed the change of formation, and at half past six in the morning, the sky began to brighten, and the commander of the Japanese destroyer squadron, the Nine Demons Kuroki, ordered: "The speed is increased to 20 knots, and the warships of the Lin Yuan troops are searched." ”

The destroyer squadron searched in front, and the four battleships and four battlecruisers hid 10 kilometers behind, according to the Japanese army's battle plan, this operation was first attacked by the destroyers, and the destroyers fired a large number of torpedoes after discovering the target, these torpedoes can sink Lin Yuan's warships best, if they can't be sunk, they will play the role of disrupting Lin Yuan's fleet.

The commander of the Japanese Combined Fleet, Heihachiro Togo, the chief of staff Mayuki Akiyama, and the representative of the United States Arms Corporation Anderson were standing in the command room of the flagship Ise at this time. Are you okay? ”

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

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

Anderson smiled helplessly and said: "General Dongxiang's technical attainments are really extraordinary, this is true, not flattery, our domestic experts are studying this topic, and there is no feasible technique that can find the location of the emission source from the received electromagnetic waves." ”

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

Anderson didn't answer, just at this moment, suddenly the communicator in front of him rang, and Heihachiro Togo saw that it was from the communication room, so he picked up the receiver and asked, "Chief of Communications, what happened?" ”

The chief of communications replied, "Report to the general, our communications have been interfered with by Lin Yuan's troops. ”

Of course, Togo Heihachiro knew that Lin Yuan's troops had the ability of electronic interference, and the chariot wing could only fight on its own under the interference of Lin Yuan's troops, and the result was a mess! Heihachiro Togo felt a chill on his spine and said, "Is the interference serious now?" ”

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

Togo Heihachiro said: "No, Lin Yuan's troops have blocking jamming machines, if we jump the frequency now, they will definitely turn on the blocking jamming, don't jump the frequency first." ”

The communications chief said, "Yes, I see. ”

Heihachiro Togo had just put the microphone back in place, only to hear Akiyama Shinyuki on the side shouting, "Lin Yuan's troops have interfered with us? It can't be, it can't be! ”

Heihachiro Togo hurriedly asked, "Why is it impossible?" ”

Akiyama Shinyuki said: "Although I don't know much about electronic technology, but I also know that if the jammer wants to accurately interfere with the target, it must aim the antenna at the target that needs to be interfered with, so that the energy of 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 that they have discovered us!" However, the radar siren did not sound, indicating that we were not discovered by Lin Yuan's troops at all, so how did they interfere with us? ”

After saying this, Anderson's face suddenly turned ugly, and Heihachiro Togo looked at Anderson and said, "Mr. Anderson, is your radar alarm malfunctioning?" ”

"No, we just checked it, and it's very sensitive to electromagnetic signals," Anderson said. ”

Heihachiro Togo said: "But Mr. Anderson, the electromagnetic interference of Lin Yuan's troops is also electromagnetic waves, why didn't your radar siren find them?" ”

Anderson said: "Lin Yuan's troops use targeting jamming, the frequency of the interference wave is close to our communication frequency, and our radar alarm device has set up a filter circuit in order not to be interfered with by the communication frequency on your warship, which can filter out the electromagnetic waves on the communication frequency of our warship and will not give an alarm." ”

Heihachiro Togo said, "But how do you explain what is happening now?" Isn't what Mayuki Akiyama said wrong? ”

Anderson said: "Chief of Staff Akiyama is right, electromagnetic interference does have to aim the antenna at the target to be interfered with, but ......" Anderson said at this point suddenly changed his voice and said, "I'll go to our operation room to have a look." ”

After Anderson finished speaking, he took three steps and two steps to the operation room of the radar alarm, and said as soon as he entered the door: "Did you receive an unfamiliar electromagnetic signal?" ”

The operator replied: "It's all background noise, no electromagnetic signals of the enemy have been detected." ”

Anderson said: "Check the alarm, is there something wrong inside, the warship of Lin Yuan's troops has already discovered us, why didn't we notice it?" ”

The operator was surprised and said, "There is such a thing?" I'm going to start the self-test circuit! As he spoke, he pressed a few switches on the operation board, and when a green light came on, the operator said: "The detection circuit shows that there is no problem with the radar alarm." ”

Anderson said, "No problem? So how can you not perceive electromagnetic waves? Turn off the filter circuit and see if it responds to our own communication waves. ”

The operator then turned off the filter circuit, and the buzzer suddenly sounded an alarm, and Anderson said: "This is strange, there is no problem with our alarm, why didn't we find the electromagnetic waves of Lin Yuan's troops?" ”

Anderson's radar siren is not bad, but they underestimate the strength of Lin Yuan's troops, Lin Yuan's radar is the J-25 airborne radar, this radar uses special technology, so that this radar has low detectability, simply put, Lin Yuan's radar can find the enemy, but the enemy's radar siren can not find Lin Yuan's radar.

To achieve this kind of performance, it depends on the high sensitivity of the receiver, and the technical background in it is very deep, although Anderson and they have invested a lot of money and energy in the field of radar technology, but their technical ability, how can it be compared with Lin Yuan?

At this time, a herald came over and said to Anderson: "Mr. Anderson, Commander Dongxiang, please go back to the command room, now the anti-missile operation is going to be deployed!" ”

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

Heihachiro Togo shook his head and said, "It's okay, as long as your interference wire can work, we can still win in one fell swoop." ”
