Yang Mingzhi knows very well that the magnetron in his hand is indeed the heart of the radar, and there are still many equipment needed to really build the radar. In addition to some necessary equipment, many seemingly inconsequential parts are also crucial to the manufacture of equipment.

The so-called radar, even if it relies on this magnetron to emit high-frequency microwaves, when the microwaves touch the object and reflect, they are detected by the receiving antenna. The oscilloscope does not exist, but the information transmitted back to the perception is still perfectly achievable.

Therefore, Yang Mingzhi explained to all the staff of the design bureau: "We will rely on this resonant cavity magnetron dismantled from the radar vehicle to build our early warning radar." Everything has to be started from scratch except for this device. We don't even have an oscilloscope, and eventually, we'll be able to perceive the noise coming from the headphones through the constant work of the listener to determine whether the noise indicates an enemy aircraft or a bird, and the direction in which it is coming. ”

This is a very backward radar, so backward that even the most primitive oscilloscopes do not exist, and even more backward than the Japanese electric reconnaissance.

It's like a blind man who uses his voice to perceive what's coming in front of him. Just when a blind person is skilled enough, he can judge by the sound that there is a puppy and a pedestrian walking!

For the Soviet troops in the swamp, only in autumn and winter did migratory birds rush to the swamp for wintering. Eagles occasionally fly in the sky, but other than that, the larger flying objects are airplanes. In this way, Yang Mingzhi estimated that as long as the radar is put into use, the listener can basically determine that this is an airplane when he hears the noise in a certain direction!

His explanation convinced the majority of designers, and they quickly hit a wall in the following designs.

Yang Mingzhi soon encountered a situation where he wanted to cry without tears, because most of these outstanding scientific and technical personnel still knew very little about radar technology!

As the main planner of this project, Yang Mingzhi pushed many things away without hesitation, insisting on doing it himself in the large office of the design bureau. At the same time, he had no choice but to act as a teacher, starting from the details and explaining the principle of radar to these young designers.

The R&D work lasted four days, and it was not until June 5 that the basic blueprint was finally summarized.

This is an early warning radar that is quite advanced even in this era.

It has a peak operating power of 100 kilowatts, operates in the 400 to 500 MHz band, and can detect flying objects from 70 kilometers away and from 1,000 to 3,500 meters.

According to the analysis of the aftermath of the air strikes, it is possible that the German airfield was near Lechtsa or Gomel. So the radar was built, and the radar station was placed in the ruins of Homnich, so that as soon as the enemy aircraft took off, it could be detected immediately. Moreover, for the German fighters and dive bombers, there was no reason for them to fly too high, and about 3,000 meters was the optimal altitude.

At the moment, this radar device, which has no name yet, exists only on a few dozen sheets of brown paper. It seems that as long as the arsenal is made according to the drawings, the radar will really be built.

Of course, the problem will not be that simple.

The biggest problem at present is no longer the magnetron, but the energy that emits powerful microwaves, where does it come from?

Do you use a generator? This has to consume precious fuel, and the troops' fuel reserves are not much, and they can't withstand the consumption of radar! Unless the radar is only intermittent, but in that case, the meaning of radar warning will not exist.

Eventually, a thought from a year ago came back to me.

"There's no way around it! To provide a stable supply of energy to the radar, we had to disassemble a generator and build a steam engine. Let the steam engine push the generator rotor and power the radar all the time! ”

Yang Mingzhi's decision was unquestioned, and finally reached the field that everyone fully understood, and the manufacturing drawings of the steam engine were quickly drawn.

They made drawings of the steam engine, as well as drawings of the large antenna of the radar.

In his plans, a radio station will be retrofitted to serve as a receiving terminal, the drawings of which have also been drawn.

Yang Mingzhi has a promising transformation of the radio station, and the US media praised it. Although he didn't have an oscilloscope, he could still get a lot of components by dismantling the radio, such as tubes that emit light. The antenna picks up the radar echo, which causes the tube to glow through the device, allowing the monitor to see the anomaly and further hear loud noise in the headphones that is far louder than the ambient noise.

In the final analysis, it is enough for the feedback received by the device after the discovery of the flying object into information that can be understood by humans!

……

Yang Mingzhi is strong, and his comrades-in-arms believe that this is a wise man like steel, a genuine combat hero, and a hero who is invincible.

However, the overwork that lasted for several days was overdrawing his body, and the bad weather also caused the temperature to continue to drop. His iron-like body will also rust under this continuous rain, Yang Mingzhi, cold.

Sick? The last time I had a cold was in the winter, so it's okay to take some medicine!

Therefore, when his throat began to feel uncomfortable, he drank more hot water, and then continued to devote himself to the research and development of radar day and night. Gradually, he began to cough, and his body became more and more limp.

In fact, since his return from the command on June 4, he has remained in the office of the Weapons Design Bureau, where he has carried out the final assault.

"I'm just having a general cold, and our main task at the moment is to complete all the drawings as soon as possible and hand them over to the arsenal. As for my body, I'll go to the hospital and inject some sulfonamides when I'm done! ”

He was the commander of the army group, and Popov and others, who were the leaders, did not dare to disobey. Besides, the chief had a very good complexion, and if he just coughed, it really wouldn't affect anything.

Undoubtedly, this was the negligence of all the colleagues in the design bureau, and it was also the negligence of Yang Mingzhi himself.

The work continued until 1 a.m. on June 6, when all the drawings were completed. In terms of scientific research, Yang Mingzhi thinks very highly of himself, and he never thinks that the Riguskov of the arsenal has greater ability, so the drawings must be drawn carefully, and the process steps must be clearly written. He supervised the whole process and personally reviewed the drawings at the end.

His mind is the best computer, and his mind is the ultimate form of this radar device.

In his plan, this guerrilla republic-made early warning radar was as sophisticated and advanced as possible, because the radar was able to move.

To this end, the troops will rebuild two trucks, one on which the main body of radar equipment is installed in its convertible compartment, and the other on which it is equipped with generators and steam engines that will serve as a source of energy for the radar. The two vehicles act at the same time, complete the circuit connection after the predetermined location, and start the long-term air scanning.

This bulky radar vehicle naturally burns peat because it is powered by a steam engine. The thick black smoke from this worst coal, which contains huge amounts of impurities, has always worried Yang Mingzhi. However, if the equipment really meets the design requirements and can detect enemy aircraft from a distance of 70 kilometers, then it doesn't matter if there is smoke. Especially when you drive to Homnich, you can even monitor the entire airspace from Mozyr to Gomel!

For the future of radar, Yang Mingzhi is full of confidence, and when it is dawn, he will personally take the drawings to the arsenal and order them to complete the finished product in the shortest time!

In addition to the excitement, he also ignored his body, and when he woke up again, he finally felt the heaviness of his body, as if he was in the deep sea. Moreover, what a wonderful figure I saw with my hazy eyes.

It's her?!
