Open an aircraft carrier to fight against Japan

Dongxiang Heihachiro said, picked up the communicator, and said: "The jamming wire transmitter, ready to activate."

Several Japanese sailors heard Dongxiang Heihachiro's order and immediately removed the two pieces of tarpaulin from the bow and stern of the ship, revealing a hedgehog-like thing underneath. Silk bag, it turns out that the mysterious thing covered with the thatch that has troubled Lin Yuan's troops for a long time is the interference wire launcher.

Dongxiang Heihachiro asked Akiyama Shinyuki: "Akiyama-kun, does anyone in the destroyer team understand electronic warfare? Can they know that we have been spotted by Lin Yuan's warship?"

Akiyama Shinyuki said: "Yes, the Ministry of the Navy has sent people who understand electronic warfare to each of our destroyers. When they see themselves being interfered, they should know that they have been discovered by Lin Yuan's troops."

Dongxiang Heihachiro said: "That's good, I don't know the situation of the destroyer team, have you found the warship of Lin Yuan's army?"

Akiyama Shinzhi pointed to the outside of the porthole and said: "Look at the sea today, there is no wind, no fog, and the sun is very abundant. Our sighting system can see very far. I believe they will definitely find the warship of Lin Yuan's army. of."

Dongxiang Heihachiro nodded lightly, and said, "Very good, God bless Yamato!"

At this moment, the chief of communications suddenly sent a message: "Report to the commander, the electromagnetic interference we have received has weakened!"

When Dongxiang Heihachiro heard this, he slapped the porthole in front of him hard and said, "It's broken!"

Anderson said on the side: "Isn't the reduction of interference a good thing? Why do you say it's bad?"

Dongxiang Heihachiro shook his head again and again, and said, "If the disturbance to us has weakened, it means that the warships of Lin Yuan's army will concentrate on attacking our destroyer team. How can this be a good thing?"

Togo Heihachiro guessed right, the Lin Yuan Fleet was going to attack the Japanese destroyer fleet. Lin Yuan’s troops knew that the shipboard radar was affected by the curvature of the earth, and the detection range was short, so they wanted to use special means to increase the detection range. The first thing they thought of was to use the atmosphere waveguide.

Strictly speaking, electromagnetic waves will only propagate along a straight line in an absolute vacuum, and refraction and reflection will also occur in different media. For example, light (light is also a kind of electromagnetic wave) will be refracted when it enters water. Under meteorological conditions, special meteorological phenomena will appear on the sea surface. This meteorological phenomenon allows electromagnetic waves to refract along the atmosphere and propagate to places blocked by the curvature of the earth, thereby greatly increasing the detection distance of radar. This is the atmospheric waveguide.

However, the appearance of atmospheric ducts is very accidental. Human beings have not been able to predict when and where atmospheric ducts will appear. Since they can't even predict, let alone man-made!So the weather officer on the Huofeng ship took the attitude of giving it a try, and tested it with an instrument for measuring atmospheric ducts, and found that no atmospheric ducts were formed, so Lin Yuan's troops could not use the atmospheric ducts to achieve beyond-horizon detection.

In order to achieve the purpose of long-distance detection of the Japanese army, Yu Feng transferred a drone equipped with synthetic aperture radar from the Vladivostok base. This drone is equipped with synthetic aperture radar. Synthetic aperture radar is a high-resolution radar. It is dedicated to imaging the target, and the UAV is flying at high altitude, so the detection distance is very far.

One hour after the drone took off and searched, it found the Japanese fleet. At this time, the Japanese fleet and the destroyer team were spreading out, and the search formation had not yet formed. Yu Feng saw that the Japanese fleet was outside the range of his own radar at this time. , and did not give an order to launch the missile, because although the missile on the Huofeng ship has the ability to be ignored after launch, the radar seeker of the missile is not powerful enough to guide the missile to hit a target tens of kilometers away, while the sky UAVs do not have the capability to direct an attack for a missile.

So Yu Feng kept waiting. During this process, he decided to attack the Japanese destroyer team first, and then attack the battleships behind. At 07:30 in the morning, most of the destroyers in the destroyer team entered the radar detection range of Lin Yuan's troops. .

Yu Feng looked at the sixteen destroyers lined up in a single line, and instantly understood: "The Japanese army formed a search formation, and their tactics are: when they find our warships, immediately launch torpedoes and call other warships to come over." , Concentrate on launching torpedoes! They want to use 'torpedo sea tactics' to cause confusion for us, and even sink our warships!"

Thinking of these, Yu Feng secretly smiled and thought: "This is not the first time we have seen this kind of tactic. When we fought against the Russians, the Russians used this kind of tactic. As a result, their communication equipment was interfered by us. The planes were fiercely suppressed, the fleet couldn't concentrate at all, and the torpedo sea tactics couldn't be used, so we beat them to pieces."

Yu Feng thought of this and ordered: "Electronic Countermeasures Department, stop interfering with the Japanese battleship group, and specifically interfere with the Japanese destroyer group! The fire control department, assign targets to each battleship, and launch missiles to attack!"

With an order, the electronic countermeasure department immediately changed the direction of the jammer to specifically interfere with the destroyer group, and the fire control department also began to assign targets to each warship. Assigning targets to warships is a troublesome thing, so it will take a certain amount of time. Taking advantage of this time, the Japanese destroyer Light Snow discovered the warships of Lin Yuan's troops.

Light snowship captain Kentaro Matsui was agitated when he heard the report of his subordinates discovering Lin Yuan's warship. He immediately said, "Advance at full speed, approach the warship of Lin Yuan's army, and launch torpedoes! Communication department, immediately notify our brother ship Lin Yuan's army The position of the warship, strike together!"

The chief of communications said, "But our communication system has been disrupted!"

Kentaro Matsui smiled coldly, and said, "Interferenced? What's there to be afraid of? Immediately use high-speed frequency hopping to send out the location of Lin Yuan's troops on other frequencies!"

The chief of communications replied loudly: "This subordinate understands!" The chief of communications immediately started frequency hopping at a high speed, hoping to avoid the frequency of jammers from Lin Yuan's troops. Knowing that, they immediately reported to Yu Feng: "Commander, the Japanese army used high-speed frequency hopping!"

Yu Feng immediately said: "Can you use blocking jamming? Completely suppress the Japanese army's frequency band?"

The troop commander shook his head and said: "Commander, this may be difficult, because the power of a single communicator of the Japanese army is much higher than our estimate. If we use large-band blocking jamming, the power required will exceed the maximum power of our jammers." power!"

Yu Feng said: "Okay, then follow the frequency of the Japanese army to suppress!"

The troop leader agreed, and then chose to follow the jamming mode. In this mode, the jammer will detect the frequency of the enemy's signal, and then adjust the transmission frequency of the machine to transmit a signal of the same frequency. However, this jamming mode has a A chronic illness, a chronic illness that cannot be changed at all.

Yu Feng frowned lightly, thinking: "If this old disease is exploited by the enemy, we may not be able to achieve the effect of interference."
