"Yes, Chief Engineer Bai, let me see how our reverse mapping is going." Mhamad said: "This anti-aircraft missile is related to how our navy and army respond to future threats. Our key project in Pakistan.”

Mhammad's words show how much he values ​​this weapon. This is also true. Since coming here, Pakistan will quickly allocate various funds needed for the project, and Pakistan will provide various parts and components needed internationally. It was quickly purchased on the market, and just two months ago, the computers here were 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 the phased array radar, and the other is the later signal processing system."

The principle of phased array radar is not complicated. The radar is divided into small units. Each unit can independently control the phase of the radar beam. When multiple units are brought together, a powerful radar wave is formed.

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

Moreover, even in China, in the 1960s, a phased array radar for long-range early warning was built and installed on a hillside.

However, these are large radars. If they want to become practical radars at the tactical level, they need to be miniaturized, mainly about the miniaturization of T/R components.

At the same time, radar also has a difference between active phased array and passive phased array. The antenna of active phased array radar is a receiving and transmitting device using T/R components. Each T/R component can generate electromagnetic waves; Passive phased array radar uses a unified transmitter and receiver, plus a phased array antenna with phase control capabilities. The antenna itself cannot generate radar waves. In contrast, active phased array radar has a simple structure. It is light in weight, and at the same time, even if some modules are damaged, it will not affect its use, and its performance is the most advanced.

The Patriot's radar uses an active phased array AN/MPQ-53 radar.

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

At the same time, on the other hand, active phased array radar refreshes a large amount of data with its fast scanning capability. This requires high-speed computers to process this data, and at the same time, complex algorithms are needed to distinguish useful information from it. If the processing capabilities are not met, even if there is a phased array radar antenna, fighters will be missed.

In contrast, the development of the missile itself plays a secondary role, and. In the development of the missile body, Mhammad directly handed over a Patriot missile to China for imitation. Pakistan's main electronic system for surveying and mapping.

originally. Measuring and mapping the electronic system is already a very difficult test, and Mhamad's requirement is not just surveying and mapping, but also requires the use of four-sided phased array radar to build an Aegis for the Pakistan Navy. The system comes with a four-sided phased array, and the data needs to be processed. It will increase geometrically, and the information that needs to be processed will become even larger.

It can be said that in this world, apart from the United States, only the Soviet Union has this capability. Unfortunately, the Soviet Union's domestic electronic technology is not up to standard, and almost all other countries in the world import the American Aegis system.

Pakistan wants to develop it itself. The difficulties will be great, but Mhammad is still confident because he knows that the Chinese Aegis will be the future generations. It was developed by China itself!

Once they have a sample, they can quickly copy it. I imported several sets of S300 systems, and as a result, my own Hongqi-9 was produced. Although there are many excuses in later generations' information about the differences between the two missiles, without the reference of the S300, Hongqi-9 is probably Like other projects, they will all fail in the end.

"This is our imitation T/R component." Bai Xue took out a small cylinder and said to Mhamad.

The flat-panel phased array radar is composed of such components. This is the basic unit.

"After we copied it, we tested it and found that there is a big gap in performance with the American-made one. For example, in terms of maximum power, if we increase the maximum power to one-fifth of the American-made one, the component will overheat, and, in In terms of service life, this component only has more than 50 hours, which is far from meeting the requirements. We are now looking for ways to improve the manufacturing process, hoping to increase 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 many years of development.

Therefore, Mhammad expressed his understanding of the current difficulties raised by Bai Xue: "We must act according to scientific laws, analyze carefully, constantly improve and enhance our technical capabilities, and we will make solid and steady progress. "

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

software! The key to the pros and cons of a weapon system is software! In later generations, Americans will not even change the hardware, but only flash a new version of the software, so that the performance of the weapon system can be greatly upgraded.

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

"Great, our software level is good." Muhammad said.

"This is of course thanks to the personnel in Pakistan." Bai Xue said: "Pakistan's higher education is very good, more advanced than ours. The computer major has trained a large number of advanced software designers. We selected a group of them to study the software system of Patriot, so it went smoothly."

If a country wants to develop, it must improve the quality of its citizens and popularize education. According to the inference of later generations, Muhammad knew that computers would change the whole world, so it was a measure proposed by Muhammad to popularize computer education now.

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

"Yes." Muhammad said, "We will benefit a lot if we understand this system thoroughly."

"Yes, we are currently conducting research. When the four phased array radars are combined, we must have a new algorithm. Otherwise, the large amount of data will make our computer system overwhelmed." Bai Xue said, "I estimate that it will take about two or three years to design the software for the four phased array radars to search the entire airspace and guide multiple missiles at the same time. By then, we will have a more powerful computer system."

Two or three years! Muhammad's face lit up. This progress is quite fast.

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

"It's not hard work. This is also for our country's national defense. Our navy is too weak now. We don't even have an advanced air defense missile in the country. We rely entirely on the introduction of French Sea Rattlers. Our air force also doesn't have long-range fighters. When our naval ships are sailing alone on the sea, the air threat is too great." Bai Xue said.

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

Next, Bai Xue took Muhammad around the entire top floor to inspect the progress of each subsystem. In order to reverse map this air defense missile system, more than 300 experts were working here.

When the inspection was completed, it was already sunset.

Standing in front of the French window, Muhammad looked at the scene outside the window. The whole earth was shrouded in a golden sunlight.

"Mr. President, are you going to eat here?" Bai Xue asked, "If you do, I'll ask the people downstairs to prepare one more."

Eating? Muhammad knew that this was almost a completely closed place. All the meals were prepared in a canteen on the first floor. In order to take care of the engineers from China, the canteen also specially invited several Chinese chefs.

"Okay, I can eat with our scientific researchers." Muhammad said enthusiastically.

"So do you eat Chinese or Western food?" Bai Xue continued to ask.

"Let's eat Chinese food."

Since coming here, Muhammad has also gotten used to eating beef and mutton all day long. However, in the future, he still likes to eat authentic Chinese food.

Many researchers are still busy. When the food is served, they eat the food in the lunch box while continuing their research.

Muhammad is holding a lunch box and looking at the food inside. This is a simple rice bowl with rice at the bottom and fish-flavored pork shreds on the top. This is a very popular dish in China.

Muhammad took the chopsticks and skillfully brought the rice bowl to his mouth. He picked up a bite of food and put it in his mouth. The familiar taste came.

"President Muhammad, I didn't expect you to be so skilled in using chopsticks." Bai Xue couldn't help but say. At this time, she also held a lunch box and sat next to Muhammad. She saw that they were all chopsticks and wanted to change a spoon for Muhammad. Who knew that Muhammad used it very skillfully.

"Yes, I can roll out the dumpling wrappers and make dumplings myself." Muhammad said.

"Really?" Bai Xue couldn't help but said, "Then I really want to see your craftsmanship."

"Okay, I'll invite you to the Presidential Palace someday to taste my craftsmanship." Muhammad said, "Even Lilith doesn't know that I'm also a master at making dumplings."

"Really? That's great, you can't forget this." Bai Xue said. Her eyes were full of joy. (To be continued ~^~)
