Chapter 448 Advantages of Active Phased Array Radar
"Xiao Fang, isn't your design... a bit too advanced?"
Three days later.
After Fang Yu explained his ideas to the team under him who was responsible for radio information.
Li Dingyuan, who came all the way from the imperial capital to help, frowned as he looked at the radar system drawings drawn by Fang Yu.
The densely packed circuit layout and antenna array arrangement on the drawings completely overturned their cognition.
"Director Li, you're right." Fang Yu put down the charcoal pencil in his hand. "But it's precisely because it's ahead of the times that it's worth doing."
There was an anxious atmosphere in the laboratory.
A dozen engineers gathered in front of the blueprints, discussing among themselves.
Some shook their heads, some frowned, and more looked confused.
"According to common sense, radar systems must go through an evolutionary process from simple to complex."
Another engineer wearing round-frame glasses said.
“Would it be too radical to jump directly to active phased array?”
"Furthermore, even in the West, this thing is only theoretical and not practical, and its performance is still unknown."
"If we rush into this radar, wouldn't it be a bit..."
Fang Yu did not answer immediately. Instead, he walked to the blackboard, picked up the chalk and drew a simple diagram.
"Directly manufacturing an active phased array radar is certainly difficult, but there's no need to worry about performance!"
"Traditional radar is like this, requiring the antenna to rotate and scan continuously."
He explained as he drew.
"It's like using a flashlight to look for something in the dark. You can only look at it bit by bit."
The engineers nodded, they all understood this.
"But the active phased array is different." Fang Yu erased the previous drawing and re-drew a square composed of dense dot arrays.
“It’s like lighting a wall in the dark. You can illuminate wherever you want, and you can illuminate many places at the same time.”
“This is truly revolutionary.”
Hearing this, Li Dingyuan seemed to be thinking about something.
“But to achieve this effect, the technical difficulty…”
"It's indeed huge," Fang Yu admitted frankly, "but we have two advantages."
"First, we have a high starting point. We are not bound by traditional thinking and can directly try the most advanced solutions."
"Second, the cost is low. As long as the core technology is mastered, the production cost is actually lower than that of traditional radar."
When the engineers present heard the word "low cost", their eyes lit up.
In this age of material scarcity, this is the most convincing argument.
"However, theory alone is not enough." Fang Yu turned and walked towards the experimental table, "We need to prove it through practice."
There is a simple antenna array model on the experimental table. This is the prototype that Fang Yu asked the workers to make according to the drawings.
Although it is only the size of a palm, it already contains the core structure of the active phased array.
"Come, let me demonstrate it to you." Fang Yu turned on the power and adjusted several parameters.
As he operated, a clear waveform appeared on the oscilloscope.
As he moves the target object, the waveform changes accordingly, accurately reflecting the target's position and movement trajectory.
"It's amazing!" the young engineers couldn't help but exclaim.
"This is not the most important thing." Fang Yu said with a smile, "Look here."
He took out a metal barrier and placed it in front of the target object.
In traditional radar, this obstruction would result in a complete loss of signal.
But in their new system, by adjusting the beam direction and energy distribution, they can still capture the blurred outline of the target.
"That's why I say it's suitable for aircraft carriers," Fang Yu explained. "In complex naval combat environments, this kind of performance is crucial."
Li Dingyuan walked forward and carefully examined every detail of the prototype.
As an old engineer who has been dealing with weapons all his life, his intuition told him that the young man was right.
"Xiao Fang," he said solemnly, "I agree with you."
"However, there is still a long way to go before this small thing can be scaled up to be used on an aircraft carrier."
"Yes, there are indeed many difficulties in building a truly usable active phased array radar." Fang Yu looked at the sunset outside the window. "However, if you want to get a tree, the best time to plant it was ten years ago. The second best time is now."
"This is the inevitable path of development, and we can't avoid it."
The laboratory gradually became quiet, with only the hum of the running instruments remaining.
Engineers are pondering the possibilities presented by this revolutionary technology.
At this moment, the equipment on the experimental table suddenly made a strange noise, followed by a puff of green smoke.
"Don't panic!" Fang Yu stepped forward quickly and skillfully cut off the power.
"This is normal. New technologies always encounter various problems, and what we have to do is to solve them one by one."
Looking at this young man who handled the problem calmly, Li Dingyuan suddenly understood something.
"People really do become less ambitious as they get older, Xiao Fang, you're right!"
"Why bother doing scientific research if you're afraid of difficulties? I'll fight you, old man, with my old bones at stake!"
Then he turned to the other engineers and said.
"Boys, starting tomorrow, we will begin a real technological revolution!"
"Everyone, cheer up and don't let anyone look down on our 301 Institute. Got it?"
"Europe!"
This sentence was like a signal, breaking everyone's hesitation.
The engineers who followed Li Dingyuan from the 301 Institute stepped forward and began to carefully study the details of the drawings.
Fang Yu watched this scene with a sense of relief. He knew that a true R&D team was being formed here.
And this is the foundation for building a truly powerful aircraft carrier...
In this way, under the leadership of Fang Yu, a groundbreaking radar system is gradually taking shape.
This will provide the aircraft carrier with unprecedented battlefield perception capabilities, allowing it to always keep "bright eyes" on the sea.
And this is just the first of many "surprises" Fang Yu prepared for the aircraft carrier...
Then, Fang Yu turned his attention to the most critical and important carrier-based aircraft that affected the combat effectiveness of the aircraft carrier...
