Chapter 277 Installing 4-array radars on sea fishing boats?
In the afternoon.
Led by Ren Feng, Wei Zhikang and his party arrived at the Yuwei ship.
When Li Yang learned about it, he hurried out to greet him.
"Hello, Captain Ren. You must have worked hard on your journey!"
"Mr. Li, you are too serious..."
After the two met and shook hands, Ren Feng introduced himself to Li Yang.
"Engineer Li, this is Wei Zhikang, the leader of the radar team of the Guangdong Coast Guard..."
Upon hearing this, Li Yang walked forward and shook hands and greeted them one by one.
After a few brief greetings, he extended his hand and invited everyone to walk into the conference room of the Yuwei ship.
It's getting late today, so Li Yang suggested starting construction tomorrow.
Wei Zhikang and others had no objection.
The guest is the host.
Anyway, before coming, Yu Zhanpeng explained clearly to them that after arriving in Yuwei, they just need to follow Li Yang's command in everything and don't need to worry about the Coast Guard General Administration.
That being the case.
How could Wei Zhikang disobey orders?
……
The next day.
Li Yang took Wei Zhikang and others into the workshop and officially started work.
Wei Zhikang asked, looking at a small fishing boat parked in the shipbuilding workshop.
"Mr. Li, is this the fishing boat that needs to debug and connect its communication system and radar system?"
This sea fishing boat looks a little small!
Yu Zhanpeng also approved them a week of official time. Now seeing the size of the ship, I'm afraid all the debugging and docking work will be completed in three days at most.
Walk up and put down the device.
Wei Zhikang narrowed his eyes and looked up and down at the fishing boat.
It must be said that although this ship is a bit small in size, the craftsmanship is still very good.
The layman looks at the excitement and the insider looks at the doorway.
He has dealt with various types of ships for many years, and he can tell at a glance whether a ship is well built.
and.
In addition to the excellent craftsmanship, the shape of this ship is also somewhat unique...
He could still understand the small high-pressure water gun on the small deck at the rear, but why was there such a large gun platform in the front, which was supposed to be a fishing seat?
Wei Zhikang frowned.
This thing seems to be only available on coast guard ships or warships, right?
Li Yang didn't see the expression on his face, nor did he know what he was thinking. He nodded and answered.
"Yes, it is this sea fishing boat."
"We have already installed all the relevant parts of the radar. Now we need your help to debug and connect them."
Wei Zhikang shook off the unnecessary thoughts in his mind and no longer paid attention to the alternative "turret".
For a moment, he thought that this 'turret' would be the kind of turret on a warship.
But think about it carefully.
This is just a fishing boat going out to sea to fish, how could it be installed with something like this?
He picked up tools and equipment and led technicians from other departments into the cabin of the sea fishing boat, ready to start debugging the radar module and install the radar scanning system used by the Coast Guard.
however……
Just as he started the radar module of the sea fishing boat, before he had time to conduct a system test, he was shocked to find out.
The radar module designed on this sea fishing boat is actually a band phased array radar!
What’s even more incredible is that…
"This... this is actually a four-sided radar?!"
The so-called four-sided array radar refers to four large fixed phased array radar antennas installed in different directions of the ship's superstructure to cover 360° airspace, thereby providing all-round air detection and early warning without blind spots.
Four-sided array radars are divided into large four-sided array radars and small four-sided array radars.
among them.
The large four-sided array radar is very huge. From the appearance, it looks like several large shields attached to the superstructure of a warship.
therefore.
The large four-sided array radar is also figuratively called the "big shield".
As the name suggests.
The effective air defense network of warships equipped with the "Big Shield" is very powerful.
The detection distance is long, up to 400 kilometers. In addition, the large four-sided array has no blind spots, making it difficult for enemy fighters to launch attacks from high altitudes, and they have to adopt a more difficult low-altitude penetration method, which greatly relieves the fleet's air defense pressure.
The small four-sided array radar is based on the large one, but is reduced in size and cost to accommodate more ships, giving the ships more comprehensive and effective air defense capabilities.
Commonly known as the 'small shield'.
but……
The four-sided radar designed and developed by Li Yang on the sea fishing boat is somewhat "neither fish nor fowl".
It has neither the ultra-long detection range of a large four-sided array radar nor the size of a small four-sided array radar.
It looks a bit like a mini version of a small four-sided array radar?
Seeing Wei Zhikang so surprised by the radar module on the sea fishing boat, Li Yang smiled and hurriedly explained.
"Engineer Wei, you misunderstood. This is not the so-called four-sided radar."
"This is just an ordinary phased array radar..."
"It only has the appearance of a four-sided array radar, but it does not have the characteristics that a four-sided array radar should have!"
Since he was planning to build a sea fishing boat and wanted to continue upgrading and modifying it, he naturally learned some knowledge about the navy's radar system.
He had seen the four-sided array radar in relevant materials and knew some searchable data.
Overall.
Compared with the four-array radar, the phased array radar designed by ourselves has many different technologies.
Although it is installed on the four sides of the cabin of the sea fishing boat, in fact, it is more to save space and maximize the use of the position of the hull, so the antenna is installed on the four sides of the outer layer of the cabin.
This way.
It can not only ensure the radar search and defense functions of the sea fishing boat, but also save other space of the fishing boat.
Li Yang's words brought Wei Zhikang back to his senses from his deep thought, and the surprise in his heart gradually subsided.
Yup!
This is just an ordinary sea fishing boat. How could it be installed with the four-sided radar system of a military ship?
I am a bit oversensitive...
The main reason is that Li Yang's design is too realistic, almost exactly the same as the four-sided array radar on coast guard ships and naval warships.
If you don't observe carefully, you will be confused.
He sneered.
"I'm sorry to make you laugh, Engineer Li, but the design of your radar antenna is really eye-catching!"
The other technicians also breathed a sigh of relief at this time.
Wei Zhikang’s reaction just now made them think for a moment that the radar system on this ship was of the same order of magnitude as that of the ships of their Coast Guard General Administration.
Fortunately, it was just a misunderstanding...
otherwise.
A civilian-grade sea fishing boat uses a military-standard radar system, and the key is that it was developed independently. How can they put their face?
Wei Zhikang didn't seem to be too curious about the radar system on the sea fishing boat, but out of caution and in order to better debug the radar system next time, he still took out professional tools.
"Engineer Li, we need to test and debug the radar system you designed before we can proceed with the next work."
"Among them, some sensitive information may be involved, such as radar scanning accuracy, ranging range, scanning frequency, angular resolution, etc. Do you mind?"
Li Yang waved his hand and said cheerfully.
"Engineer Wei, go ahead and test it. It won't cause any trouble..."
Wei Zhikang nodded, without hesitation, turned on the equipment and prepared for testing.
however!
As soon as he started the machine and tested the first data of the fishing boat, Wei Zhikang was shocked by the data displayed on the screen...
