"Yes, Chief Engineer Bai, let's see how our reverse mapping is going," said Mhamad. "This air defense missile is related to how our navy and army respond to future threats, and is our key project in Pakistan."

Mhamad's words showed how much value this weapon is, and the fact is that since we came here, Pakistan will quickly allocate all the funds needed for the project, and Pakistan will quickly purchase the various parts needed in the international market. Just two months ago, the computer here was updated to the latest model.

"We are now in the research stage." Bai Xue said: "We are facing two main problems in reverse development, one is the t/r component of phased array radar, and the other is the late signal processing system."

The principle of phased array radar is not complicated. It divides the radar into small units. Each unit can control the phase of the radar beam separately. When multiple groups are gathered together, it forms a powerful radar wave.

Since the electric scanning method is used, the refresh speed is greatly accelerated.

Moreover, even in China, in the 1960s, phased array radars were built for long-range early warning and installed on one hillside.

However, these are large radars. If you want to become practical radars at the tactical level, you need to miniaturize this radar, mainly about miniaturization of the t/r component.

At the same time, radar also has the difference between active phased array and passive phased array. The antenna of active phased array radar uses the receiving and transmitting device of the t/r component, and each t/r component can generate electromagnetic waves; while passive phased array radar uses a unified transmitter and receiver, plus a phased array antenna with phased control capabilities. The antenna itself cannot generate radar waves. In contrast, the active phased array radar has a simple structure and a light weight. At the same time, damage to some modules does not affect the use. The performance is most advanced.

The Patriot's radar uses an/mpq-53 radar with an active phased array.

The imitation of this radar is one of the key contents of development.

At the same time, on the other hand, the active phased array radar refreshes a large amount of data with its fast scanning capability, which requires a high-speed computer to process this data. At the same time, complex algorithms are required to distinguish useful information from it. If the processing capability is not achieved, even if there is a phased array radar antenna, the fighter will be missed.

In contrast, the development of missiles itself has become a secondary position. Moreover, in the development of missiles, Mhamad directly handed over a Patriot missile to the Chinese side for imitation. Pakistan mainly surveying and mapping electronic systems.

Originally, surveying and mapping the electronic system was already a very difficult test, and Mhamad's requirement was not just surveying and mapping. Instead, it was necessary to use four-sided phased array radar to build a Pakistani naval Aegis system. The four-sided phased array will increase in geometric multiples, and the information needs to be processed will be even larger.

It can be said that in this world, except for the United States, the only Soviet Union has this ability. Unfortunately, the electronic technology in the Soviet Union is not up to standard, while almost all other countries in the world import the American Aegis system.

It will be very difficult for Pakistan to develop it by itself. However, Mhamad is still full of confidence because he knows that the Chinese Aegis shield in later generations was developed by China himself!

As long as they have samples, they can quickly copy them. When they imported several sets of S300 systems, they were created with their own Hongqijiu. Although many parties defended the differences between these two missiles in later generations, if they did not have the reference of S300, Hongqijiu would probably be like other projects and would eventually die.

"This is our imitation of the t/r component." Bai Xue took out a small cylinder and said to Mhamad.

The phased array radar of that flat panel is composed of such components, which is the basic unit.

"After we imitated it, after testing, there was a big gap between performance and American products. For example, in terms of maximum power, we added at most one-fifth of American power, and this component will overheat. Moreover, in terms of service life, this component is only more than 50 hours, which is far from meeting the requirements. We are now trying to improve the manufacturing process, hoping to improve the power and heat dissipation capabilities." Bai Xue said.

This basic component restricts the performance of the radar. A mature active phased array radar requires years of development.

Therefore, regarding the difficulties that Bai Xue has encountered now, Mhamad expressed his understanding: "We must use scientific laws to do things, analyze carefully, and continuously improve and improve our technical capabilities. We will make solid progress and steadily advance."

"On the other hand, our progress is still good," said Bai Xue. "We have deciphered all the software of the Patriot missile system through disassembly. Now, we are studying these software, hoping to understand all the functions and improve them on this basis."

Software! The key to the advantages and disadvantages of a weapon system is software! In later generations, Americans could not even change the hardware and just flash the new version of the software, which could greatly upgrade the performance of the weapon system.

Disassembly is a common way to study software systems. In order to pursue high efficiency, programs are still written in assembly language. Disassembly is the way to decipher programs.

"That's great, our software is good," said Mhamad.

"Of course this is thanks to Pakistan's personnel." Bai Xue said: "Pakistan's higher education has been well carried out, even more advanced than our domestic ones. The computer major has trained a large number of advanced software designers. We have selected a group to study Patriot's software systems, so it went very smoothly."

If a country wants to develop, it must improve the quality of its people and popularize education. According to the inferences of later generations, Mhamad knew that computers would change the whole world, so it is a measure proposed by Mhamad to start popularizing computer education now.

Pakistan has a large population base, and many computer geniuses will definitely be born in such a large population. Now, a good start has been made. The software elites trained by Pakistan have begun to serve the national defense system.

"No," said Mhamad. "We will benefit a lot if we understand this system thoroughly."

"Yes, we are now conducting research. Together, there must be new algorithms. Otherwise, a large amount of data will make our computer system unable to bear it." Bai Xue said: "I expect that it will take about two or three years to search the four-sided phased array radar for the entire airspace and guide multiple missiles at the same time. At that time, we will have more powerful computer systems."

Two or three years! Mhamad was delighted, and the progress was quite fast.

"Thank you for your hard work, Chief Engineer Bai." Mhamad said.

"It's not hard, it's also for our country's national defense cause. Our navy is now too weak. There is not even an advanced air defense missile in China. It relies entirely on the introduction of French sea rattlesnakes and our air force does not have long-range fighter jets. When our naval ships are sailing alone on the sea, the air threat is too great." Bai Xue said.

After the research was made, Pakistan and China shared technology. Mhamad had no objection to this point. Pakistan's national interests were closely linked to China.

Next, Bai Xue took Mhamad and walked around the entire top floor to inspect the progress of each subsystem. In order to reversely survey and map the air defense missile system, more than 300 experts are working here.

When the inspection was completed, it was already sunset.

Standing in front of the floor-to-ceiling window, Mhamad looked at the scene outside the window, and the entire earth was shrouded in a golden sunshine.

"Mr. President, are you planning to have a meal here?" Bai Xue asked, "If you eat, I'll ask you to prepare one more."

Have a meal? Mhamad knew that this place was almost a completely closed place, and all the meals were prepared in a canteen on the first floor. In order to take care of engineers from China, the canteen also specially hired several Chinese chefs.

"Okay, I can have a meal with our researchers." Mhamad said enthusiastically.

"Then are you eating Chinese or Western food?" Bai Xue continued to ask.

“Eat Chinese food.”

Since he came here, Mhamad has been accustomed to eating beef and mutton all day long. However, in later generations, he still liked to eat authentic Chinese cuisine.

Many scientific researchers are still busy. When the food is delivered, they continue to do their own research while eating the food in the lunch box.

Mhamad held a lunch box and looked at the food inside. It was a simple rice bowl with rice underneath and topped with fish-flavored shredded pork. This is a popular popular dish in China.

Mhamad skillfully put the rice bowl to his mouth with his chopsticks, picked up a bite of the dish, put it in his mouth, and a familiar smell came.

"President Mhamad, I didn't expect you to be so skilled in using chopsticks." Bai Xue couldn't help but say. At this time, she was also sitting next to Mhamad with a lunch box. She saw that they were all chopsticks and wanted to change a spoon for Mhamad, but who knew that Mhamad was extremely skillful.

"Yes, I can also roll out the dumpling skins and make dumplings by myself." Mhamad said.

"Is that true?" Bai Xue couldn't help but say, "Then I really want to see your skills."

"Okay, I'll ask you to go to the Presidential Palace and try my skills." Mhamad said: "Even Lilis doesn't know, I'm a great idea to make dumplings."
