The military-industrial scientific research system of the academic master.

As one of the economically developed key cities in the Yangtze River Basin, Jinling actually has many flights to the capital every day. Logically speaking, Chang Haonan can just ask the college to buy him a plane ticket like he did when he first went to Shengjing.

But after experiencing a series of previous events, Chang Haonan is naturally no longer that unknown little person.

For example, the most obvious point is that in order to ensure safety, all his air travel will be handled free of charge by United Airlines, which has an Air Force background.

Chang Haonan himself was happy to save the trouble and boarded a Boeing 353 aircraft operated under the name of flight CUA737 in the afternoon.

This flight is real. It flies from Beijing to Chancheng via Jinling, but it is not open every day. The three airports it passes through, Nanyuan, Daxiaochang and Shadi, are all military-civilian airports under the jurisdiction of the military, which is very suitable for Chang Hao. Nan traveled without making too much noise.

Xu Yang, who was going to Jinling with him, also took advantage of the opportunity and experienced the first-class cabin operated by United Airlines.

However, the price of her air ticket is still provided by the 14th school, but she only has to pay the price of economy class.

Of course, despite the name, by the late 90s, first class on most short-haul aircraft had essentially become business class with upgraded hardware.

"The Electronic Technology Group is so rich, can they buy first-class flights for both of us?"

Xu Yang put his carry-on luggage away, and then felt the seats that were more spacious and softer than those in the economy class.

She didn't know the inside story. She was only told about the upgrade when she came to the airport to exchange her ticket, so she naturally thought it was an arrangement made by Jinling.

"It's okay. Although Dianke Group's benefits are indeed good, I don't have to spend money to fly. Besides, even if we don't upgrade, they won't be able to sell many tickets here."

Chang Haonan said, flattening the seat to nearly 180° and preparing to take a rest.

In this era, there are only a few people who can afford to fly, and even fewer passengers will spend money to buy higher-end cabins.

As a result, those who ended up flying first class were mostly those like Chang Haonan who didn't spend any money, or at least those who got upgraded without spending money like Xu Yang.

"Is it okay if you don't have to spend any money?"

In two days, Xu Yang had become accustomed to the various surprises brought by Chang Haonan, so he did not show any surprise, but only said half-jokingly:

"If I had known there would be such a good thing, I would have joined your Aviation Industry Group after returning to China."

Apparently she thought this was a benefit within the aviation industry system.

Chang Haonan did not clear up the other party's misunderstanding, and replied in the same joking tone:

"It's not too late if you want to join..."

……

When the plane landed, the 14th Institute of Electrical Engineering naturally arranged a dedicated person to pick it up.

It’s just different from the common 212+Coaster configuration here in the north. Jinling uses the 212+Iveco Deyi which is full of local characteristics.

Before Chang Haonan's rebirth, this kind of light passenger car had few users except for centralized procurement and use as a special vehicle chassis. However, from the 90s to 2010, Iveco was a popular model all over the country.

As expected, the person leading the team was Guo Lin, who had met Chang Haonan and the other two.

"Guo Gong moved very quickly. I thought I would have to wait for a few days."

The three of them shook hands and got into the car.

Xu Yang sat in the same double row seat as Chang Haonan very naturally.

"As soon as the people inside the institute heard that it was you two that we were going to invite, they approved the note without saying a word, for fear that something might delay us."

Guo Lin signaled the driver in front to drive:

"Should we take a break first or what?"

Chang Haonan turned his head and looked at Xu Yang beside him, who just shrugged and said he didn't care.

"After you put your luggage away, let's go take a look at the pod first. Researcher Xu and I wanted to see what this high-end American gadget looks like along the way."

"no problem."

The 14th Institute of Electrical Engineering is only about 20 kilometers away from Daqiaochang Airport. There were basically no traffic jams in the 90s, and it only took about half an hour to reach the destination.

After getting off the car, the two entered a building under the leadership of Guo Lin, and then turned around several times before finally seeing the captured pod and 14 more in a place that should be the basement. of other staff.

The workplace is not a place for small talk, so after just a brief exchange of greetings, Chang Haonan and Xu Yang put on anti-static lab coats and had close contact with their research subjects for the first time.

"In the past few days, we have basically completed the splicing work of these fragments. Although the function is definitely impossible to restore, at least the overall appearance should be similar to before it was broken."

Guo Lin followed behind the two and introduced.

The moment he saw the pod, Chang Haonan was basically sure that his previous guess was correct.

Putting aside the synthetic aperture radar antenna in the middle, this is an electronic jamming device based on digital radio frequency memory (DRFM) technology.

Xu Yang, who was next to him, also found the key point almost at the same time:

"There is no traveling wave tube or CNC phase shifter in this. If you are sure that you didn't miss it during the search, then this thing should use a relatively new all-digital design."

It is no different from Chang Haonan's judgment.

The latter did not do it rashly, but asked the staff next to him to remove some shell fairings that partially blocked the view, revealing the true appearance.

"But... the design of this pod is so bloated."

Xu Yang frowned slightly when he saw the whole interior, and seemed a little puzzled.

"When we were searching in the mountainous area, we also thought it was very strange, but we can be sure that at least there are no large pieces missing. This thing should have been designed to look like this."

Guo Lin explained from the side.

Chang Haonan, who was circling the pod wreckage, was also surprised.

Having lived through the Internet age, he has seen pictures of the insides of the AN/APS-154 Synthetic Aperture Radar (SAR) pod and the AN/ALQ-99 electronic jamming pod. Although the lower half is basically empty, the equipment is filling up. There is still a level of about 60%.

But the thing in front of me is at least 10 meters long, and only the front and rear ends and the middle section are equipped with equipment, and the rest are empty shells——

Perhaps due to power supply or weight constraints, the SAR antenna inside the pod is only about 4 meters long, which does not fully utilize the space.

Logically speaking, this kind of tactical equipment should be as compact as possible.

"Anyway, let's use an optical amplification device to check the circuit design first. I see that the memory has been smashed, so there should be no possibility of restoring the program code."

Chang Haonan decided to put aside his doubts for the time being and start from a more reliable place.

When he first entered the laboratory, he was worried that any special equipment would be needed, but the circuit boards at the core of the interference part were not large in size and only required an ordinary optical microscope.

High-end scientific research often requires only the simplest tools.

"Phase accumulator, waveform memory, low-pass filter, reference clock..."

Although Chang Haonan has never seen these component models from the 90s, it is still not difficult to judge their functions through some appearance features and vague inscriptions on the surface:

"Yes, this board is a direct digital frequency synthesizer."

"Under the control of the reference clock, the phase accumulator linearly accumulates the frequency control word K, and the obtained phase code (n) addresses the waveform memory (ROM) so that it outputs the corresponding amplitude code, which is passed through DAC and low-pass filtering Then the corresponding analog signal can be output.”

Chang Haonan looked up from the binocular microscope and found Guo Lin next to him and his colleagues looking at him with incredible eyes.

"what happened?"

"This... just... can be seen directly?"

Guo Lin looked at Chang Haonan, who looked as if he was just eating and drinking, and then at the huge pod that had just been put together next to him.

He suddenly felt that his previous work seemed a bit in vain...
