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

This is a joke that researchers can easily understand.

In addition to being used as a verb to stand out, highlight, and emphasize, some academic journals also require authors to sort out the eye-catching points in the paper content and write them at the beginning of the paper, which is also called highlight.

Even if you have not engaged in scientific research, this word, like the Chinese name "Gaoming", can be easily associated with the mission characteristics of early warning aircraft.

In short, it fully meets Wang Xiaomo's requirements for "Chinese and English puns".

Of course, the name is not the point after all.

For a project with such high new technology content that it is likely to exceed 70%, the most important thing is to be able to proceed step by step.

Otherwise, it is easy to confuse the priorities and end up with a messy outcome.

Therefore, although this is an almost completely foreign trade-oriented model, it still needs support from higher-level units.

Even if China Electronics Technology Group Corporation and China Aviation Power Corporation Limited could come up with a certain amount of funds, it would be difficult to coordinate the strength of other systems.

Furthermore, the technology of optically controlled phased array radar will ultimately serve China's own national defense construction.

The foreign trade model is just a by-product of the technical verification process, and it plays a role in increasing revenue and reducing costs as well as collecting user data.

Therefore, Chang Haonan and Wang Xiaomo hit it off and quickly put together a feasibility report, explaining the application prospects of the idea of ​​controlling microwave signals with optoelectronic signals and optoelectronic components from both theoretical and engineering perspectives.

Then submitted it together.

……

a few days later.

Commission of Science, Technology and Industry for National Defense, in the director’s office.

Ding Gaoheng had been staring at the report of only about twenty pages on the table for some time.

That's right, just watch.

It's not reading.

Because I haven't turned the page for about twenty minutes.

What's more, he has read the report over and over again no less than ten times since he received it.

Except for the mathematical formulas, it may be an exaggeration to say that I can recite it backwards, but I think it should not be a problem to recite it forward.

Before serving as the director of the Commission of Science, Technology and Industry for National Defense, Ding Gaoheng had long been engaged in the research and development of inertial devices and navigation systems.

Although it sounds unrelated, this research direction actually involves dealing with other detection systems including radar.

As for control systems and control theory, they can be considered my main profession.

Therefore, he used to think that he "knew a little about radar".

However, today, he began to doubt this self-perception——

It seems like...

I don't know much about radar...

"Comrade Xiaomo, Comrade Haonan."

Ding Gaoheng sat up straight, looked away from the report on the desk, and looked at the two people sitting on the sofa on the other side of the office:

"I know that a few years ago the United States proposed a next-generation destroyer research and development plan called DD21, in which a key component is DBR, dual-band radar."

"Is our multi-band radar... a similar concept to the American DBR?"

DD21 is actually the famous DDG1000 Zumwalt-class destroyer.

We are actually still in the final stage of bidding for the project.

Anyone with a little vision can see that the proposals put forward by Boeing and Raytheon will most likely win.

On paper, the various technical and tactical indicators of this new destroyer are quite advanced.

After all, it is 2001 now—

Even though the United States in this timeline has encountered many additional setbacks in the military, political, and economic fields compared to its previous life, few people still doubt its strength in the technological field.

Even the most foresighted people would find it hard to imagine that after entering the 21st century, the industrial level of the United States would experience an extremely outrageous cliff-like decline.

If someone said at this time that the US military's "next-generation equipment plan", from the LHX Comanche helicopter, the XM2001 Crusader self-propelled artillery, the JSF joint attack fighter, to the CG (X) cruiser, and then to the DD (X) destroyer, the LCS littoral combat ship... would all end hastily or end in failure, he would probably be regarded as a lunatic.

In short, at this moment, when people are developing new equipment, they will still unconsciously compare it with similar concepts of the US military.

but……

After all, Chang Haonan is not among them.

"The dual-band radar of DD21 actually combines an S-band and an X-band radar on a common information processing back-end device, which is equivalent to using one back-end to control two front-ends at the same time."

"Our multi-band radar concept uses the same set of hardware from the front antenna to the rear I/O device to achieve collaborative operation of two or more bands."

"So... from a principle perspective, it is much more advanced than DBR."

This description made Ding Gaoheng's heart beat a few times.

After all, he is already 70 years old, and it is hard for him to handle such a big surprise:

"So, should we transmit electromagnetic waves of several different frequency bands at the same time, or deploy multiple sets of transmitters/receivers and then flexibly switch between different bands according to needs?"

"Well...it depends on the specific application scenario."

Chang Haonan explained:

"Because signals of different frequencies can be separated, this is technically feasible."

"However, transmitting and receiving signals in multiple bands at the same time will put a lot of pressure on the back-end information processing process, so it is more suitable for platforms that are not sensitive to size and can deploy sufficient computing power, such as large early warning aircraft, fixed radar stations, and radars on large and medium-sized ships."

"For fighter jets, vehicles, or small and medium-sized ships, their back-end processing capabilities may be limited, so they can also work on the same frequency band at the same time and switch as needed."

"Also, even in the latter case, there is no need to set up multiple transmitters/receivers."

After Chang Haonan finished explaining, Wang Xiaomo continued to add:

"The radar front end can be made exactly the same as the previous one, just use adjustable frequency selective permeability material on the radome."

"For example, I can transmit X-band and C-band signals at the same time. When long-distance detection is needed, the radar dome selectively transmits the C-band and absorbs the X-band. When precise locking is required, the opposite is true."

Originally, according to Wang Xiaomo's understanding, for a fighter jet, the field of view should be more important than the bandwidth.

However, Chang Haonan said that the phased array radar of a fighter jet can also be deployed on a rotating base to expand the effective illumination range by changing the angle, but the ultra-long-range detection capability brought by the C-band is difficult to achieve by traditional airborne radar.

However, the size of a fighter jet makes it difficult to process wide-band signals simultaneously.

It's not even just a limitation of computer power.

That’s why the idea of ​​a second “optional frequency” came into being.

"Then... I think there is nothing to hesitate about."

Ding Gaoheng closed the report and said:

"The funding for major projects will only be available after approval from the higher authorities. However, at the level of our Science and Technology Commission, we can allocate a portion of the funds from this year's advanced technology research and development fund for your use."

"In addition, if you need to coordinate with units in other systems, you can report directly to me, or to the new deputy director Li Zhongyi, who is currently in charge of external liaison work."
