After Elder Huang saw that the students had already entered the state of class, he began to explain the engineering and design of the super unmanned vehicle.
"We just mentioned the use of super unmanned vehicles on the battlefield. What is a super unmanned vehicle?”
"Is the unmanned vehicle as simple as installing a turret that can be remotely controlled on the tank?”
"Although the unmanned vehicle has to enter the battlefield after obtaining air superiority and the first wave of air strikes, and at this time, the enemy has almost no heavy armored tanks that can pose a threat to the unmanned vehicle, if an unmanned vehicle can't even be discovered by the hidden enemy anti-material snipers and personnel holding anti-tank missiles, is it going to be a live target?”
" Therefore, even if we are thousands of miles away, our operators must be able to accurately control the battlefield and control the unmanned vehicles!”
At this point, Elder Huang took out his thermos cup and took a sip of tea before continuing his explanation.
"To accurately control the battlefield environment of the unmanned vehicle, it is necessary to use solid-state laser radar, white light camera, thermal imaging video system, millimeter wave radar and other detection equipment.”
"Today, we will talk about the solid-state laser radar used by unmanned vehicles.”
"The laser radar's ranging principle is TOF. Simply put, it determines the distance between two objects through the flight time of the laser signal. This kind of radar technology is mature, but its anti-interference ability is weak.”
" There are many problems that we need to solve when using this radar on unmanned vehicles, such as interference from rainy days, foggy days, and strong natural light. Also, TOF cannot provide speed-related data, so we need to install an additional millimeter wave radar.”
" For example, the TOF radar can detect a person in front of it, but it can't determine how fast the person is running. This makes it difficult for our unmanned vehicle's machine gun to pre-aim and hit moving objects. Another example is a fallen leaf floating in the air. Since it can't detect the falling speed of the fallen leaf, it's difficult to determine whether it's a fallen leaf or an obstacle..."
" To solve these problems, we need a new type of radar. First, let's look at the composition of a simple radar: It has a rated voltage of 12V, a reduction ratio of 1:30, a maximum speed of 300 revolutions per minute, and a 500-wire optical eraser installed at the end of the motor…"
On the podium, when Elder Huang started talking about the super unmanned vehicle as a whole and talked about a small radar equipment, everyone was stunned.
When Elder Huang talked about the overall structure of the unmanned vehicle, they could still nod silently.
However, when the unmanned vehicle was divided into countless parts and the technology and principles contained in each part were explained separately, everyone was dumbfounded!
This was because this was not something that ordinary freshmen could understand.
From morning to noon, Elder Huang had been talking non-stop about how to design a radar suitable for super unmanned vehicles.
"When the laser radar is working, the probe needs to rotate continuously. Here, pay attention to the signal transmission between the probe and the base.”
" Here, I'll teach you a way to solve this problem with a conducting slip ring. There's a set of brushes inside the conducting slip ring, which can solve the entanglement problem of the signal wire when it's rotating. You must remember this..."
Hearing Elder Huang's voice, many people began to doubt their lives.
They hadn't fully understood the direct current deceleration motor that Elder Huang had taught in class, not to mention that he had taught dozens of technologies similar to conducting slip rings.
However, compared to everyone's confusion, Ye Bai kept writing and drawing in his notebook.
According to Elder Huang's explanation, Ye Bai not only mastered the knowledge of laser radar with his full level of comprehension, but he also drew a radar structure diagram on his notebook. He even had his own ideas for improving the TFO radar.
After listening to Huang Shi, an academician of the Dragon Country's Academy of Engineering, explain the laser radar, you have an epiphany and have completely mastered the relevant knowledge of the laser radar!
Through Huang Shi, an academician of the Dragon Country's Academy of Engineering, you have gained an epiphany and mastered the design and manufacturing scheme of an overclock phased array multi-line all-situation radar!
Through listening and being taught by Elder Huang, Ye Bai not only mastered all the knowledge, but the thoughts in his mind were also becoming clearer.
A normal radar only had a laser detector and a receiver. It could only detect the distance of the obstacles, but it had no way of detecting the height.
But now, Ye Bai had come up with a design plan for an overclock phased array multi-line all-round radar through some of the techniques taught by Elder Huang during his lecture and various epiphanies he had gained from his top-level comprehension.
Not only could his overclock phased array multi-line all-round radar measure distance through overclock changes, but it could also obtain the target's speed and distance information through the changes in reflected light. Moreover, because Ye Bai's improved light source was strong enough, the filter was smaller, and the detector would only accept the light emitted by him. Therefore, the anti-interference ability was more than ten times higher.
Moreover, through the integration of the transmitter and receiver, multiple laser beams were obtained through the rotation of the motor. The more laser beams, the clearer the surface outline of the object was, and it was easier to distinguish. It could even achieve full situation awareness.
In layman's terms, it was like the superhero movie Lone Ranger. It could display the rough outline of the human body in the mind by using the sound of raindrops hitting the human body when it rained. Ye Bai's overclock phased array multi-line all-round radar was just like that.
Whether it was adults, children, or vehicles, their outlines and movement speeds could be accurately displayed on the radar map!
"Class dismissed!"
At 12 o'clock sharp, all the students went numb when Elder Huang announced the end of the class.
This was because they realized that apart from the few words that Elder Huang said when he first arrived, they could understand the rest of the morning.
However, compared to the others, Ye Bai was a little ecstatic.
Not only had he mastered the knowledge of radar in the morning, but he had also comprehended new technologies through the various tricks taught by Elder Huang.
"Elder Huang is worthy of being a prominent figure in the military industry. Not only is his lecture easy to understand, but every problem is often pointed out to the point. He always gives the simplest and most effective way to solve technical problems!”
Ye Bai sighed.
However, after hearing Ye Bai's words, Ye Bai's roommates were instantly speechless.
This kind of heavenly book level lecture could actually be said to be "easy to understand"?
However, Ye Bai didn't bother with them. Instead, he hurried to the cafeteria to eat, and then returned to the dormitory to study the overclock phased array multi-line all-directional radar.
In the mornings that followed, Ye Bai went to Elder Huang's classes very enthusiastically.
Furthermore, he maintained the frequency of mastering a new knowledge and comprehending a new technique every day.
"October 12th, you listened to Huang Shi, an academician of the Dragon Country's Academy of Engineering, and had an epiphany. You have mastered the relevant knowledge of the thermal imaging video system!

November 10th…
Within a month, the students of the Weaponry Engineering major were visibly haggard and listless.
The mentality of not understanding anything and still having to go to class every day was simply an extremely painful torture.
Ye Bai had not only mastered more than 30 subjects of knowledge in this month, but he had also comprehended and improved more than 30 new technologies. This was definitely the most fulfilling month he had ever had since he came to the Defense Technology University!
