Open an aircraft carrier to fight against Japan

After a night of sailing, everyone was hungry, so Tao Zheng reached out and took one, and said, "Well, if you have filial piety, this matter doesn't need to be reviewed by the whole ship. Write an inspection and submit it separately." Just give it to me."

Li Kai sent the buns to everyone while apologizing, Lin Yuan looked at the buns in the paper bag and smiled, and said, "Is what you said true?"

Li Kai looked at Lin Yuan, and said in a panic: "Shuai Lin, don't talk so much, you eat buns." Then he put the paper bag in Lin Yuan's hand, Lin Yuan took it and glanced inside, and said : "Didn't you buy your steamed stuffed buns for us? I know that the steamed stuffed buns made by Xiaofeng Ship Canteen are [-] in a drawer, but there are only nine steamed stuffed buns left in your paper bag. If the steamed stuffed buns are really bought for us Yes, why would you eat six yourself?"

Li Kai said with a playful smile: "I was really hungry, so I left here to have breakfast. Anyway, Captain Wu didn't give the order to start the radar search, and I didn't delay anything."

After listening to Li Kai's words, Tao Zheng sneered and said, "Write a review and read it aloud at the ship-wide meeting the day after tomorrow."

Li Kai immediately begged for mercy, and Lin Yuan hurriedly said, "Okay, that's fine, wait until I'm gone, turn on the radar, and let me see how it works."

When Li Kai heard this, he put Baozi aside, and then turned on the power of the radar operation screen. The screen flickered, and after about ten seconds, the azimuth disc, distance gauge, and a countdown clock appeared on the screen. There is also a line of English letters below, Lin Yuan pointed to the line of English letters and asked: "Old Ma, what does that line of English letters mean?"

Ma Zhiliang replied: "This stage is the power-on information prompt stage and the magnetron warm-up stage. During this period, the radar system will conduct a test on itself. If there is a problem inside the radar, it will be prompted on the screen. Now the English letters on it It means 'no fault'."

Lin Yuan smiled and said, "Why use English? Is Chinese not good?"

Ma Zhiliang replied: "I didn't think too much about it. It used to be in English, so I designed it in English."

Lin Yuan said: "In our era, the instructions on all kinds of advanced equipment are in English, that's because they are the country that develops advanced equipment, but in this era, we are the country that develops advanced equipment, so we have to The English on the above has been replaced with Chinese, which is not only convenient for our people to use, but also foreigners must learn Chinese when using our equipment in the future!"

Ma Zhiliang nodded and said, "Okay, I've remembered, we will change the equipment for the next batch."

Lin Yuan smiled, and then looked at the radar screen. At this time, there was another line of words "Start" on it, and then the radar screen lit up, emitting light green fluorescence, and many flashing bright spots appeared on it. Lin Yuan Pointing to those bright spots, he said, "Those are the echoes of the waves."

Li Kai said: "That's right, the threshold displayed by the radar is too low, so small echoes like sea waves are also displayed on the screen. I adjusted the display threshold to be higher, so that small waves will not appear. "As Li Kai said, he pressed a few buttons, and soon the flickering dots on the screen became less and less.

Lin Yuan pointed to several radar screens nearby and said, "What are those screens for?"

Li Kai said: "Those are all functional screens. My screen is the general search screen. The search distance on it is the largest, about [-] kilometers. My screen is only tens of square centimeters, and I use a screen of tens of square centimeters to display it. For a target of tens of kilometers, the error is too large, so when I want to measure accurately, I will send the target's situation to a few screens on the side, where it will be displayed in detail."

Li Kai pointed to a flickering light spot and said: "Look at this light spot. Based on my many years of experience in operating radar, I think this should be a big ship, but this light spot is too small. I’m not sure about its radar reflection area either, if I want to know the details of this light spot, I’ll select this light spot and send it to the screen next to it.”

Li Kai said and pressed a few buttons, and then he saw the screen on the side light up, and only the light spot was displayed on the screen, and there was also information on the radar reflection area, distance, azimuth, and speed of the light spot on the side, Li Kai Kai walked to the edge of the newly brightened screen and pressed a button. At this moment, he saw a bright line connecting the flashing spots. Li Kai pointed to the bright line and said, "This screen also has flight tracks drawn. Function, it can judge the course of the light point target according to the position of the light point flashing."

Lin Yuan nodded, and then asked: "It is impossible for us to deal with only one target during combat, so you must not be busy alone. What about the operators of other screens? Where have they all gone?"

Li Kai said ashamedly: "They are all my subordinates. When they saw me going to have breakfast, they all went..."

Tao Zheng patted Li Kai on the back of the head lightly, and said angrily, "Look at the good deeds you have done, the upper beam is not straight and the lower beam is crooked!" These operators were a little scared when they were caught leaving their posts without permission. Just as Tao Zheng was about to start the training, Lin Yuan said, "Today we only catch the culprit, and don't care about the threats!"

Li Kai smiled wryly: "Captain, I know I was wrong..." Li Kai frowned as he spoke, but suddenly frowned, and said, "It's not right!"

Tao Zheng said angrily, "What kind of tricks are you pretending to play again, brat!"

Li Kai said innocently: "I'm not pretending, but there is something wrong with this ship!"

Lin Yuan hurriedly asked: "Is there a problem? What's the problem?"

Li Kai said: "The course of this ship is wrong. The ships here are either going west to Weihai, or going north to Tianjin, but this ship is going northeast. The destination seems to be our Lushun Port!"

As soon as this remark came out, everyone was surprised. Lushun, as the base of the Beijing ship, does not allow merchant ships to enter. Then what is this ship and what is it going to do in Lushun? Lin Yuan asked: "Could it be that the ship appeared? malfunctioned."

Li Kai pointed to the reflective area on the side and said: "Look, Lin Shuai, this reflective area is [-] square meters. With such a large reflective area, combined with the situation of ships in this era, it must be a sailing ship, and it is also a ship. A sailboat with a huge sail area, our wind direction today is due west, even if it breaks down, it should be blown westward by the wind!"

Lin Yuan thought: "Then what kind of ship is this ship? Why did it go to Lushun Port? Unfortunately, radar is not a camera, and it is impossible to see the optical image of this ship from a long distance!" Lin Yuan said: "Adjust the antenna Position, aim at the direction of that ship, increase the antenna gain value, I want more detailed information about that ship."

Li Kai stretched out his hand and pressed a few times on the operation panel, and several other operators also started to act. One operator said: "Report to Commander Lin, the target position is 35, the distance is [-] kilometers, the speed is [-] knots, the distance [-] nautical miles from Lushun Port!"

Tao Zheng said to Lin Yuan, "Why don't we take the mocking windship over there and have a look?"

Lin Yuan thought to himself: "It's still dark now, and the Zhongrui and Jingzhong ships that use optical reconnaissance methods can hardly see that ship, so we can't let them go. Since the ship is heading towards Lushun Port, let's go and see it." look."

Lin Yuan then used the radio to contact the captain Wu Xinghai: "If you find a suspicious target, please go to the target sea area quickly! The azimuth hole is [-], and the distance is [-] kilometers!"
