The people at the testing ground where the radar vehicle was located let out an astonishing roar, but unfortunately, their "Ula" was eventually suppressed by the even louder noise!
"Damn it! What kind of sound is this? My eardrums are about to be torn!" The noise was so loud that Salinchkin covered his ears and cursed, his whole expression distorted.
Yang Mingzhi, Yevlov, etc., even the four radar soldiers in the listening room.
The radar soldiers headed by Diana finally witnessed this miraculous moment. Their watches were the same time as Homnich's, without a second difference. In fact, Diana, who had been wearing headphones,
At the sixth second of the experiment, she noticed that the electron tube, which symbolized the "existence of obstacles," began to flash red. Before she paid close attention, just ten seconds later, her ears heard a squeaking noise.
.
This is just the beginning!
As time went on, the noise got really bad, so much so that she took off her headphones altogether.
There is no need to wear headphones anymore. Thanks to the tweeter, the noise feedback converted from the radar echo is already broadcast to the entire blacksmith village!
Two thousand meters above Homnage, a hundred dandelions are slowly falling. Thanks to the breeze, they are falling slowly while floating to the north, and at the same time they are constantly reflecting radar microwaves.
The radar with a power of up to 600KW, through its ten-meter-long large antenna, perfectly received these echoes. The four girls in the monitoring room, their momentary ecstasy quickly turned into distorted expressions, and they also used their hands
Covered his ears.
The culprit was indeed the radio speaker.
In fact, as long as the four girls moved their hands and took the microphone away, the violent noise would disappear. In this case, Diana was still very smart. In desperation, she grabbed the rope that was about to make a move.
Erkina put her head against her ear and shouted: "Stop! We want the people to know that our radar is a great success!"
No one stopped the tweeter from continuing to spread the heart-rending noise. What's worse, the noise actually got stronger and stronger!
This is actually because the reflective surface composed of floating "dandelions" is completely maximized and the reflectivity reaches its peak.
Therefore, the noise originating from the northern part of the Blacksmith Village quickly spread throughout the entire Blacksmith Village. The vast number of soldiers and civilians had no idea what was making such a shrill noise, as if a large group of cats were scratching the wall. People felt uncomfortable all over, and some even
I feel like my heart is trembling abnormally.
However, not everyone can rely on their patience to endure this damn noise.
This annoying noise finally made Yevlov unbearable. The reason is simple: it has no intention of stopping.
He quickly rushed out of the auditorium, and emotionally grabbed the collar of Yang Mingzhi, who was standing in front of the tweeter and calmly covering his ears, and asked in the loudest voice he could: "What on earth is going on with you?! This
Can’t the noise stop?”
Unfortunately, Yang Mingzhi almost only saw Yevlov’s big mouth and howling. “You! What did you say?!”
"I mean...me!"
After all, Yevlov was considered a reckless man, and the noise really drove him crazy! He simply pulled out his revolver in front of Yang Mingzhi, ignoring the surprise of his old comrades, and pointed the gun at the wooden hanging
The horn on the pole was emitting a crazy noise and all the bullets were fired.
The bullet silenced the loudspeaker and saved tens of thousands of people from mental pollution!
Yevlov was obviously still angry. He was breathing heavily and continued to ask: "What on earth is going on! This noise almost killed me!"
"So! Why don't you just beat the horn into a hornet's nest?!" Yang Mingzhi slowly let go of his hands, with a wicked smile on his lips!
"Yes! I would rather be blown up by the Germans than killed by this damn noise."
"Then don't you think about it, what does this noise mean?"
When asked this question, Yevlov was stunned. Even though he knew almost nothing about radar and telegraph machines, he knew before the experiment that when the noise came from the loudspeaker, the experiment was successful.
Next, Yang Mingzhi became excited. He grabbed Yevlov's shoulders with both hands and shook him violently: "Dear Davarich, we succeeded! The radar was successful! Even now, we can receive the radar
Echo!”
To be honest, the success of radar did not excite people like Yevlov and even Salinchkin. After all, they are not scientific workers. Their attitude towards the loudspeaker noise was that they were happy at first, and then they hoped it would
"Shut up." Obviously, Yevlov saved everyone, but when everyone quieted down, they had to face this embarrassment - how to repair the damaged speaker?
The arsenal was naturally responsible for repairing the horn, and Liguschkov had no time to care about it. During this period, he and his wife had been shouldering all the pressure caused by the radar. Although the horn was broken, the equipment in the radar monitoring room was
Still intact!
The two men paid no attention to officers like Yang Mingzhi and took the lead in getting into the listening room.
And just entering this listening room with fairly good soundproofing effect, the uncomfortable noise like a hundred cats scratching the wall is still echoing in my ears.
The husband asked straight to the point: "Comrades! Are we still monitoring the whereabouts of those rockets?"
The appearance of the two people also surprised Diana. She is a person who has been in the world, and she immediately replied: "Yes! You see, the red light of the tube is very bright, and you can hear the noise without wearing headphones. This shows that,
There are a lot of obstacles high in the sky in the direction we are aiming at. These must be experimental rockets. They fall so slowly that we can always receive radar echoes."
"That's great!" The husband stamped his feet happily. This experiment has been a great success so far!
But the person who really has the right to make this experiment a success is Yang Mingzhi himself. He stepped into the listening room, faced with the noise and shining lights, and the excitement in his heart made it difficult for him to stand. The space here is not small.
, he sat on the chair and took the headphones from Diana with trembling hands.
Just picking up the headphones made the noise louder, so he didn't damage his eardrums.
"Alas! It's a pity that we don't have an oscilloscope. If the microwave is fed back on the oscilloscope, you can see straight lines that suddenly turn into mountain peaks, that is, a very strong signal is received! Poor us, we can only use this kind of damage
Use your ears to feel the results of radar detection.”
The commander's words were a kind of summary, and Diana thought they were an encouragement. She stood at attention and swore: "Commander, don't worry, no matter what difficulties there are, we will continue to work hard!"
"Very good! Now do some responsible operations."
"Ah?" Diana was thinking that the commander had any other words of encouragement, but unfortunately she didn't.
"This experiment has been successful on the surface, but now I need more objective evidence. Now control the remote sensing and start the automatic rotation of the antenna!"
